Unless there's a really good reason for leaving out those features, I'd
put them in. I'd be more than a bit annoyed to sit at a machine, say "Oh
goody, netcat! I'll just run my bizarro udp super-server-hammer and we'll
see where the problem is." and then discover that my favorite diagnostic
scripts no longer work.

Maybe static-linking would be good. I've used netcat to resurrect some
horribly-mangled machines in which not much else worked. Nice as a quick
and dirty server or client.
