font-lock-punctuation-face covers all punctuation.
The rest (bracket, delimiter, misc-punctuation) are for the more specific
kinds, with misc-punctuation being anything not a bracket or
delimiter. For example, see bash-ts-mode which specifies $ as
misc-punctuation.
Oh... kay? So "misc punctuation" is punctuation which is not punctuation?
IIUC `font-lock-punctuation-face` is a "parent face" for all forms of
punctuation, and then each actual punctuation is expected to use either
the delimiter, bracket, or misc face.

Ah. That would make sense.

Maybe it would be better to remove font-lock-misc-punctuation-face, though?

People can still use font-lock-punctuation-face for everything punctuation-like that doesn't match the category of "brackets" or "delimiters".

Just like font-lock-doc-face inherits from font-lock-string-face, or font-lock-comment-delimiter-face inherits from font-lock-comment-face.

We don't seem to have a practice of "parent faces" which are otherwise unused. font-lock-punctuation-face's docstring doesn't suggest this kind of purpose either.
