I also don't care that much how much code is changed; if it must be changed, then change it to what is best, which may not necessarily be the minimum change.
If an asynchronous sched domain rebuild is needed in some places, then consider just using it everywhere, rather than providing two code paths to rebuild, one sync and one async.
Ask not how we got here; ask where we should be.
In particular, and in this specific case, having the dual code paths really did make it a little more difficult for me to understand the code, as evidenced by the back and forth discussion on how to name the confusingly similar functions. Such naming controversies are usually a sign of code duplication or improper factoring.
That additional difficulty in understanding this code was a key factor in delaying my review of your code. I'd look at it, my mind was glaze over, and I'd put it aside for a few days. This happened repeatedly.
Fine code is like fine art ... spare, elegant, compelling in its expression.
