Title says all, it checks with file-remote-p and the hardcodes /bin/sh.
It should ideally check the login shell of the remote system or... but
that all needs knowledge it's not supposed to have, I guess. Hmm, but
file-remote-p does use a handler system. So... have to ponder (if it's
not completely changed in 25)
At least document it, and please give a way to override in the "Use
shell-file-name, I know what I'm doing".

`shell-file-name' is often wrong for remote systems; there could be
another OS, for example. "/bin/sh" is POSIX and can be assumed to exist.
How shall one know the remote login shell in advance?
And, in order to find a proper solution, maybe you could show a use case
where "/bin/sh" is simply wrong?
Best regards, Michael.

Actually, POSIX doesn't hardcode the location of sh. File system layout
is not part of POSIX.

Right. I meant, that one can expect a POSIX compatible shell at "/bin/sh".
