I have seen it occasionally done in other cases. Maybe one objection in opening and closing statements. The only trial I remember it happened on a regular basis was in the Arias case and objections were made constantly by the defense team. It was maddening how many objections they made but that is highly unusual. In fact it is highly unusual that a Judge would allow that many objections in opening and closing statements.
If they do object it is like you said and the presiding Judge will tell them openings are evidence and then they move along.
Imo, it is better if the Prosecutor doesn't object. They will have a chance to dispel the 'blame the victim game' through witnesses from the witness stand.
However; I hate detests attorneys who puts the victim on trial and I believe these jurors will too. The subject is totally irrelevant anyway because under no circumstances did he have a right to murder Mrs. Carter. Its just used as a diversionary tactic hoping the jury will be sidetracked by irrelevant BS.
I believe Beverly loved her husband deeply and believe it or not many married women want to still look good for their husbands no matter how many years they have been together.
May justice be done in this very sad case.
