Hmm... but if a package does that in an ELPA archive (i.e. the
`:lisp-dir` thingy appears in the `archive-contents`), then this package
will not be installed correctly when installed with an older
Emacs, right?

IOW, it's an extension of the ELPA protocol.

I do think it's getting time to update the protocol based on the
experience gained over the last 10 years, but I'm really not convinced
`:lisp-dir` is a good addition.

E.g. a thing I'd find more interesting would be to let the tarball provide
its own <PKG>-autoloads.el (which is in charge of adding whichever
lisp-dirs it wants).
