What is the reason for this change? None of the FooPullback.apply() have the domain kwarg. So this is "missing" in what sense? I'd expect all other pullbacks that extract the domain from the expression require the same change then.

What do you mean, all the Piola pullbacks do this, see here for example:

ufl/ufl/pullback.py

Line 318 in 8275654

domain = domain or extract_unique_domain(expr)

This pullback was neglected by a recent PR #303 that introduced this new kwarg in apply().

Ah, all good, I was looking at the UFL before that PR.
