Unfortunately, HP went missing in mid-October yet LEO did not begin sifting through the landfill until the end of November. Consequently, it is likely LE searchers had to dig deep into the rumble to get to the garbage from the day when she went missing, Sunday, October 17, 2021.
By this time, can we due to decomp, expect possible long bones or the skull to be found? I'm not familiar with many cases that involved landfill excavations, especially when such a long time lapsed between her going missing and when the search began. 6 weeks later, is a guess.
Landfill Search Began Nov 29, 2021 (?)
LAPD searching landfill for evidence in Heidi Planck’s disappearance

I agree that difficult decision may need to be made. I don't envy those who would have to make it. But I disagree with the statement "They've been doing it for well over a month."
I don't think we know exactly how long they have been searching the landfill. At least I don't. But it seems to be generally agreed LE began the search on Nov 29. And here is a Dec 9 link suggesting that the search had to be called off because of rain.
Stormy weather suspends search for Heidi Planck's body in landfill
While LE didn't make a big announcement about the search suspension due to rain the way they made an announcement about the initial start (although lots of articles about the soon-to-resume search refer to "December rain" calling it off)
it sounds like the initial search may have lasted slightly less than 2 weeks. (Nov 29-Dec 9 is 11 days including weekend days.) I don't think we know whether they went back to the search after the Dec 9 suspension but my guess is no.
And so whether the search might need to be permanently suspended IMO depends not on the time passed since Nov 29 so much but on how much of the DTLA/H&F trash dumped in the area during the critical period has been searched. We're all aware the search didn't begin for over 40 days after the purported fatal "incident" at the H&F so there could be lots of more recent trash in the general area. But after the trash area where Oct 17-18 trash would have been put has been searched, it doesn't seem more searching of trash would make much sense. But I don't think they've been actively searching the landfill for anything like "over a month."

Tons upon tons of trash, heaps and heaps deep, for weeks upon weeks was dumped where they are searching bc of the time lapse you mentioned; however, we hope they are fruitful. Locating a piece of her anatomy would be beneficial.
Perhaps they are searching for evidence and proof of drugs, used for sedation, or laced with something bad such as Fentanyl that the culprits discarded along with HP. There's some fierce fermenting going on in the Landfills. But, I'm optimistic.
Possibly they've had a team of criminal profilers from Quantico come in to present a prepared profile to the Lead Inv. LAPD needs to know what type individual would harm HP, or if she came to her fatality in some manner of overdosing, ie.; then, who would opt to toss a body down a trash chute?
Hence, their tasks include forming a list of possible suspects, IDing a suspect(s) but, in the least, determine who had access to HPs life, for it to tragically end in such a hazardous place as the area they're painstakingly searching come Monday, imoo.
WTH would place HP in a trash chute of an exclusive building and expect to get away with it? Why was Ms Maz frightened and violent, even? The time frame is tight that the unsubs are limited. They need a geofence warrant, perhaps, to find out who was in the area when it concerns HPs demise.
To be frank, this theory of HP being placed into a trash chute, and perhaps, getting stuck, had been on the forum Reddit for almost since the MP report. This is not news to most of us. Evidently, most of the residents have known since Day One or so and D Day for Heidi going missing.
After all the concussion-giving Maserati Lady says so, and, also, that she saw HPs body stuck in the chute. Horrors

This is true crime of the kind we just can't make up.
All jmhoo
