Put simple, filters can only use what transports offer. Sure, if
transports could process message flags, filters could easily use
them.

Save knows nothing about the transport. It generates a file address,
thus requiring a file transport to process it.

First hack the transports for message flags, then add code for filters
to use them. And in order to hack transports, first find out how each
daemon implements message flags for each message store it can use, and
find a structure to represent all that.

I don't say it can't be done. It just requires some work, reading IMAP
server sources to begin with.
