There are a couple of configurations of systems for NetBSD where swapping
is unnecessary, or even undesireable. The Sun 3/50 "Xterminal" and some
diskless NC configurations come to mind.

How well does UVM deal with not having any swap space?

How hard would it be to properly support such configurations (i.e. no
hangs, crashes, etc, if RAM exhaustion hits)?
