I'd say it's worth it, and I imagine other new dwm users will too,
every now and then. When something running in monocle mode has the X
server tied up, whether grabbed or caught up in some buggy behaviour
and you're trying to kill the offending app, what do you do? Hold
down keys, like everyone does sooner or later, right? They will
repeat, and those repeats will be saved by the server and faithfully
executed by dwm.

If you hold down alt-J you'll end up with a completely arbitrary
window on top, if you hold down shift-alt-C you'll kill everything on
the tag and any other active tags, and if you hold down shift-alt-
return to try to get a terminal to kill it with... Well, a few days
ago I ended up with what I think was over 100 aterms running on my
PDA. :) There were 53 on tag 2 at least. I just killed the X server,
I didn't even look at the tag where the troublesome app was.

As an aside, dwm makes a brilliant window manager for my PDA, I feel
silly for not trying it before. Only 4 tags so as not to crowd the
title bar and monocle mode as the default, and it's just right.
