That's not an excuse for turning sieve so heavy that many if not most

Not every ISP will want to support all Sieve extensions. They don't need
to. Many ISP will probably refrain from allowing regex use, of
variables, for that matter. I think it's perfectly OK to create Sieve
extensions that are explicitely not suitable for all Sieve use cases.
E.g. the envelope extension can't be used in MUAs since that
information in general is lost on final delivery. OTOH, people will
want to have execute command/play sound actions (the latter could be
added to notify) on the client.
I agree, though, that the I-Ds currently floating around should first be
advanced to RFCs before proposing even more extensions. It's a bit too
much currently ;-)
They [RIAA,MPAA] are trying to invent a new crime:
interference with a business model.
