True. The only benefit is it works by default. That is, without having to
override $TMPDIR. That's not good enough.

When testing whether it would also work with a customised $XDG_RUNTIME_DIR
(even if another special case), apparently I made a mistake and failed to
notice that gnome-terminal doesn't inherit that env var either (and yes,
that's a problem caused by gnome-terminal).

Understood.

At Fedora some people still think that Claws Mail should hardcode a
directory for the socket file. That would avoid the problem altogether,
but I don't know why the file is put into system tmpdir instead.

Btw, I'm also giving another try at getting Fedora /usr/bin/firefox changed
so it doesn't mess with $TMPDIR. That won't fix gnome-terminal mailto handler,
but is the lowest-hanging fruit, IMO.
