I'm fairly sure that client-side filters are what most people use, so
the point is moot. I know Cyrus supports Sieve and I heartily wish Evo
did too (it's been repeatedly requested over the years) but it doesn't,
so you have to use some out-of-band client to access it.

A Sieve plug-in would be welcomed by many, but note that people
accessing multiple servers are still going to need client-side filtering
until every server in the world supports Sieve, something I don't see as
ever happening.

Returning to the original point, certain operations on folders are not
updated to the server instantly, so you can get apparent inconsistencies
between multiple instances (which in the fullness of time will resolve
themselves as long as everything keeps working).
