Not sure what you're talking about, the 2822 oddities like
quoted strings and quoted pairs with some strange stuff like
embedded NO-WS-CTL or embedded spaces ?

In that case it's fine from my POV if you say "NO", anything
that's so complex that we only find it in the errata of 3696
is completely unusable for normal user.

OTOH if you say "NO" to percent-encoding where necessary -
like always for UTF-8 at least in the LHS - then I'd think
that this could be a mistake.  And for some characters you
need it anyway - I'm not sure, what about say "#" i the LHS ?

Sure, you don't need to support UTF-8 immediately.  But when
it's available in some years it could be nice, e.g. the Czech
example in the Jabber URI draft:

        <xmpp:ji%C5%99i@%C4%8Dechy.example/v%20Praze>

The part ji%C5%99i@%C4%8Dechy.example could be a future IMA.

Sure, all I said was "don't limit it _unnecessarily_ now".  Bye
