I'm in favour too, but I'm also in favour of using it in the CAPABILITY
string as well. My reasonings:

1) I'd rather minimize the syntactic differences.

2) If a server advertises an appendlimit prior to authentication but wishes
to indicate no limit subsequent, there is currently no method for doing so.
I have no clue why a server would wish to do this, but the specification
seems adamant that changing the limit after login (rather than not
advertising it prior) is useful.
