Wrappers which make things simpler are always useful, but the lack of
wrappers does not justify a wholesale replacement.

We all know that lockdep has limitations but I yet have to see a proper
argument why this can't be solved incrementaly on top of the existing
infrastructure.

That said, I'm not at all interested in a wholesale replacement of
lockdep which will take exactly the same amount of time to stabilize and
weed out the shortcomings again.
