I think that's more a case of a franchise spliting off into two separate continuities rather than backtracking
Which could maybe still be the case with Star Trek. Maybe the movies will continue with the alternate universe, and maybe a series would be in the prime universe. It probably wouldn't happen that way if the Bad Robot team controls the TV series though. I think it's too hard to say since a TV series doesn't even seem likely for the next few years. There's a lot of variables.
As for Terminator, well, I think Cameron said it best when he said that the soup had been pissed in.
