I don't want or expect it to move into a DAW. I've got a couple that work just fine.

The idea of a frozen section is that all tracks in that section are frozen. So, what else is to keep track of?

If you wanted to Alt+8 one of those frozen tracks in the section, well while you were doing so that track would revert to unfrozen and when you were done it would reconfirm to its brethren.

Even so, that's not the idea. The idea is one section or more of bars is at the moment foresee-ably finished/ done/ perfect/ etc. and you don't want to mess further with it ... but later if you change your mind you still can.
