True, but universal support isn't found anywhere these days (Try
browsing to your average online banking site with IE2, or signing up for
a Hotmail account without images enabled), but as long as clients are
updated every few years, they can probably keep up.

Are there any reasonably modern clients that can't do some form of SMTP
AUTH at this point? -- I'm pretty close to disabling POP before SMTP on
my network and forcing SMTP AUTH. One more abuse issue relating to POP
before SMTP and I'm throwing the switch.
I can still whitelist by IP if I need to, or even for a specific
mailbox/domain, but frankly, I haven't needed to for anything except my
Palm, and a quick software update added SMTP auth support there too.
