That sort of refactoring being one of the best reasons to keep things
out of individual drivers!  Having said all this I don't know if it's
worth blocking Jean-Francois' work on that, it's an improvement in
itself.  Splitting the code out a bit would be good to help prepare but
having the full refactoring done might be too much of a blocker.
