As I wrote before, in general, I do like this approach; however, the
implementation in this series seems to make the code longer, which
kinda defeats its purpose of simplifying the implementation. It could
be because the series is mixing fixes with restructuring. Can you
please re-spin the restructuring part once fixes are settled? Let's
see if that actually makes things simpler.
Thanks!
