Re-using as much code as possible was definitely the way to go.

I can see no issue with integrating an updated compatibility layer, except
if it breaks all existing drivers, which I presume it doesn't. :-) So this
step of your plan could take place without any design discussions.

Again, I don't see why there would be discussions necessary. Re-using the
code made sense, IMHO.

That's a no-brainer. But every driver must be tested to make sure it works
correctly.

That's the part where some discussion could and should take place. I am
looking forward to that. Is someone already working on the integration with
(one of) the network preflet(s)?
