To the extent that Emacs-29's new `major-mode-remap-alist` can be used
to select which mode to use, we can indeed leave the original modes
as-is.
Another argument in favor is that it's a bit tricky to make `<foo>-mode`
both the parent mode and the standard entry point: we do that for
`tex-mode` but the implementation is ugly.
[ If it weren't for this implementation problem, it would be my
favorite choice. So maybe the better option is to add specific support
for that in `define-derived-mode`, where we could implement it
cleanly and thus also fix the ugly gymnastics of `tex-mode`. ]
OTOH it's a bit jarring to have the generic term `<foo>-mode` refer to
a specific implementation.
For that reason, my preference is for:
- `<foo>-<abstract/parent/base/common>-mode` as the shared parent.
- `<foo>-mode` as a dispatch function that calls the appropriate specific
major mode which could be `<foo>-ts-mode`, or `cc-<foo>-mode`, or
`<foo>-with-JSX-mode`, or ...
