Right, that's why I wrote about "subtle" differences.

Sure. But lately I was plagued with recursive loading of Tramp packages,
so I'm a little bit conservative in moving code between the different
files. 

Whenever it is possible to refactor code out I'll do. *-process-file is
on the list, but I cannot promise to do it immediately. One idea is to
generalize `tramp-send-command' and friends, for most of the handlers
this is the major difference between the different backends. Other
handlers but *-process-file would profit from this as well.
