The work you committed in 9.2 (?) to re-plan generic paths appears to
have resolved the vast majority of that problem. Certainly to the point
where it's no longer worth retaining a whole new protocol just for the
purpose.
At least, that's my opinion on the matter - Dave's the one doing the
vast majority of the work on the driver, so it's his opinion that'll
really count, but I'll be surprised if he isn't pleased by anything that
shrinks and simplifies the driver. I've CC'd him.
