I commend your use of URIs, however I still can't see what clear utility 
the proposed 'acct:' scheme brings to the broad internet community, 
beyond that which is already available.

What requirement is fulfilled by the 'acct:' scheme that isn't already 
handled by other schemes?
What does it enable, or what is gained by it's use?
What other techs might it make possible?

If there is a real gap for a scheme which can be used to mint 
identifiers for the class of things which are user accounts, then 
shouldn't that need be looked at closely and it be determined whether 
the scheme specification is open and robust enough to stand the test of 
time?

  acctURI      =  "acct:" userpart "@" domainpart

This seems very limited, if acct: is to be rolled out at internet level, 
then why not open it up more, certainly acct:twitter.com/webr3 may be 
useful, are fragments useful, how many of these questions have been 
looked at, and how deeply has this new scheme been considered beyond the 
very specific use case it's been designed to work for/around?

I'm not trying to knock or stall anything here, just to nudge towards 
the notion that it may be either (a) unneeded, or (b) needed and 
possible to improve/generalise to add even more utility.

Best,

Nathan
