Hmm.. if real RTs are coming to utility tracks soon, I think they should act as normal RT mixer tracks. If there is no content or it(they) are frozen they would not regenerate by default?

As I am getting used to new mixer, it lets you select which tracks are present in the mixer. I assume the ones are not selected, will not regenerate.

But, sure +1 to have that option for loyal customers that have slow machines. I guess a more of comfort safeguard thing... If that is slowing development.
