I don't think the registry is redundant: it enables some
"bootstrapping" that would otherwise require writing procedural code.
Essentially, the overall "meta-profile" is defined via the three
registries: required / forbidden tools, import steps, and export steps.
IIRC, extension profiles are not properly *supposed* to override the
base profiles tools, precisely for this reason. They are not really
designed to be "reversible" either.
The "add-on" use case people are trying to shoehorn into extension
profiles is not really appropriate, especially if "reversion" becomes
part of the deal.
