no, the only improvement from my proposed text with dead:beef:cafe is that 
we isolate new-weird-characters like [:] to "diagnostic stuff" - we don't 
write anything that lets sites name themselves dead:beef. And I think 
discussion has shown that [] doesn't make the problem worse, so I see 
little argument for not using them if we use them elsewhere.

There are only 3 ways I see to get rid of the : character:

- Stop putting domain-literals in Path: at all (seems unacceptable)
- Encode IPv6 addresses differently (seems unacceptable)
- Treat IPv6 and IPv4 differently (seems unacceptable)

If you've eliminated the impossible, what you're left with.....
