Hi Adam,

We have something similar for the release process (RELEASE_TESTERS.TXT), so it should be fine to have a list of people that volunteered to be bugged when sub-architectural decisions are needed.

If we go down that route, I suggest not to re-use CODE_OWNERS.TXT, because that's already a big mess. Maybe we could move all target owners from CODE_OWNERS to lib/Target/OWNERS.TXT and keep it hierarchical, so we can have multiple owners per target (as we already have in some).

Feel free to start this RFC on the mailing list, though, as this is not a discussion for this patch. :)

cheers,
