That's a huge change for a relatively small benefit, but if this is
approved by the I2C core maintainer then fine with me. For:

Agreed, it's huge. The benefit isn't really measureable, the motivation
is to improve the situation for driver authors who with the change
cannot make wrong assumptions about what to return in .remove(). During
the preparation this uncovered a few bugs. See for example
bbc126ae381cf0a27822c1f822d0aeed74cc40d9.
