That's very much false in my opinion and experience. A program definitely
*doesn't* know the signal dispositions it starts with, so if it *needs*
something specific, it'd better do it itself. It might be basic courtesy not
to mess up with signals for your children, but they definitely can't have any
expectation.

I disagree here too.

Well, in my session (Xfce) signal dispositions are reset anyway, so SIGPIPE is
not ignored.
Also note that lightdm by itself doesn't setup the signal dispositions so it's
likely to happen somewhere in the underlying libs. Any help finding where
would be appreciated.
