Thank you for the well-written document!

I'm concerned about the user experience of this extension. 

I imagine confusion will arise when the opaque :mailboxid takes precedence over the human readable mailbox name.

Or is there useful advice to provide to the Sieve UI implementer, like "this is for special cases and should probably be off by default"?
