I think BBCLASSEXTEND is very useful.
However last time I tried (2-3 weeks ago) there were still issues with
BBCLASSEXTEND and packaged staging.
Never really got the time yet to dig into it (and also it is quite
time-consuming to create a faulty situation).

Also I've no idea on how to actually verify that the change is ok and
blindly adding
BBCLASSEXTEND = "native"
and removing the -native recipe does not seem wise either.

Have you tried to do it according to the instructions?
If you want to do it according to the instructions given it takes
quite some time per recipe.

Also if you do one thing, it does not say you should not do the other.
I'd say it could be an and-and situation.

Furthermore by cleaning up the recipes it is clear where things need
to be done (so we avoid that someone wastes time on a recipe that is
outdated/obsolete anyway).
(and removing an obsolete recipe + native variant improves the parsing
time twice as much as BBCLASSEXTEND-ing it).
