Yes that would be great.

I remember somebody reporting terrible performance while committing
a single changeset to the linux repository; something like 20 minutes.

Also some more effort should be put into decent GUI tools (yeah, i`m
promoting myself here too, not on purpose as well :-)
So far it didn`t seem there is any observable interest to work on that.

The problem i see here is that there is one major obstacle for folks to
go the arch way: Linus not using it as well.

Therefore they have to go in all sorts of trouble with the arch<->patch<->bk
patch translation process.
