I think that it would definitely be beneficial to give them more information, as opposed to less. The jurors I have talked to have very often had a lot of questions about things, like what the eventual sentence was going to be or why they didn't hear about this sort of evidence. When they've been allowed to talk to the judge in some sort of debriefing afterwards, they can often get those questions answered. They might not be able to do that, depending on whether it raises a legal issue and so forth.
In many cases, one of the things that does bother jurors is not knowing some of the things, like what you are talking about, so I think it would definitely be helpful.
What works against that to some extent is that after the trial is done some of the jurors are just done. For however long the trial has lasted, they've given over a significant part of their lives to dealing with this. They're behind on work. They've had to pay a babysitter for extra time. When I have tried to collect data on jurors after the trial, it's been a pretty even split. About half of them are very eager to talk about it and the other half say they have given their week over to this and they just want to get home and deal with all the other stuff they have to deal with.
Those are going to be competing factors.
