But tramp files are special-cased also when it comes to restoring
the desktop after an Emacs start: They are not restored (at least
not by default).  I think it is fair to assume that probing a file
every five seconds through SSH is more critical than probing a local
file.

Moreover, I have dozens of local version-controlled files open but I
open a remote file only seldomly.  Without special-casing, the whole
workflow suffered due to a rare use case.

Tschö,
Torsten.
