Done now.

I'm not aware of any such way. The code explicitly checks the syntax
to be 'word' or not 'word'. But maybe Stefan has some insights?
You could, of course, make a wrapper command that would modify the
syntax table before invoking the real thing.
[Message part 3 (message/rfc822, inline)]
1. emacs -Q
2. (insert "Foo_bar")
3. M-% foo RET quux RET
4. Observe the buffer contains Quux_bar
5. Undo, so the buffer contains Foo_bar again
6. M-% foo_bar RET quux RET
7. Observe the buffer contains quux
Expected behavior:
7. Observe the buffer contains Quux
It seems to me that this would match the docstring better:
Replacement transfers the case pattern of the old text to the
new text, if both ‘case-fold-search’ and ‘case-replace’ are
non-nil and FROM-STRING has no uppercase letters.
