Actually I might as well had done this. However, I had nothing to
write to stderr anyways and it seems cleaner this way: the file
descriptor is open and points to the tty, so why not use it?. Bonus
feature: you may redirect it to another tty for -say- debugging.

Anyways, I doubt anyone redirects stderr to /dev/null by default,
much less for an interactive program. You could (maybe should)
redirect stderr in the command you use to feed slmenu its options
(unlike say for dmenu, which usually just pollutes your
.xsession-errors a bit). Either way, slmenu does not print its UI
until it's finished reading stdin, same as dmenu.
