To be clear, the two are functionally equivalent; but if you'd prefer
it written that way then I'm happy to make that change.

I'm not certain what you're asking here.

With respect to the manual entry being discussed here, we could
trivially show code to `require' all of the tramp-* libraries prior
to calling trace-package or trace-regexp. e.g.:

(mapc 'require '(tramp tramp-adb tramp-cache tramp-cmds
                       tramp-compat tramp-ftp tramp-gvfs tramp-sh
                       tramp-smb tramp-uu trampver))

(or else something which automatically locates library names starting
with "tramp-" and loads them all).

Perhaps you're actually be suggesting some kind of `eval-after-load'
tracing behaviour, though?
