      But Emacs is inconsistent in how
    non-letters in REGEXP are treated.

    BTW, this inconsistency was not present in Emacs 19.34.

What people expect in case propagation is inconsistent; it depends on
semantics that only an AI could understand.  So there is no chance
we could make this always work.

Consistent implementations tend to be wrong very often.  I made
changes in order to produce results that people expect in more cases.
(Sorry I don't remember which cases--it was too long ago.)
