I'm sorry, but "accessing web sites from browsers and web services from
applications" isn't "a corner case".
The fact is that almost everyone with an Internet connection at their
home or business would be perfectly happy with ports 80 and 443 working
well and nothing else. Perhaps the occasional random UDP for VoIP (to a
hosted VoIP service that relays all traffic anyway) but even that isn't
strictly necessary if your TCP 80 and 443 are working well. Even the
POP/IMAP and SMTP ports aren't needed any more, as web-based mail
clients are all the rage.
Would this be true if there hadn't ever been NAT? We'll never know...
but it the architecture in use today, and NAT and strict firewalls don't
break it at all.
