This makes sense to me now. Thanks for sticking with me. I've even gotten
it to work, and it's extremely fast compared to focus stacking, which makes
me think the 15 seconds or so that it takes to do an in-camera focus stack
is mainly spent on processing rather than exposing.

Two sides to a coin to me, although I suppose I think about backgrounds
more because I'm generally unwilling to spend a lot of time on backgrounds
in post. I generally bracket (the old fashioned way) from f5.6 to f11 to
see where I get the best compromise of DoF and good background. I guess
I'm saying they are never really separated for me.

I assumed it was something more proprietorial than focus breathing per se.
Not all mZ lenses seem to work, which suggests design is a key. Do you
happen to know if any Panny m43 lenses will focus bracket on an Oly camera?
