jka-compr-handler, epa-file-handler and file-name-non-special are
left. All of them have their reason.
And there are packages out in the wild, which add other handlers. Like
jarchive--file-name-handler and sweeprolog-file-name-handler, I've
checked only (Non)GNU ELPA. All of them would suffer from the
bind-file-name-handler-alist-to-nil trick. There's a reason we haven't
documented it in the manuals.
And this is just the case to handle it in Lisp code, with
without-remote-files. According to the last Emacs Survey, more than 50%
of Emacs users don't use Tramp, never ever. But they must live with the
useless checks in file-name-handler-alist for Tramp. All of them would
profit, if they add (inhibit-remote-files) in their .emacs file.
Best regards, Michael.
