The problem is that none of the Tramp package's code is executed before
building the autoloads file.  So if we want to fix the problem in
a seamless manner for the user I suspect we'll have to do something like
add an `emacs-29.1-fixup` package to GNU ELPA and add it to Tramp's
`Package-Requires:`.
