That's more in line with some of our other delegate-pattern uses, and it keeps it from being a temptation to start abusing the field. We could also some day in the future allow Sema to take ownership of arbitrary external sources as well, though that's clearly not a goal right now.
I agree that Sema should take the ownership it's external source (or at
least we it should be specified with a flag while setting it). For
example the ASTContext owns its ExternalASTSource.
My original intent was to try to keep the semantics (which is was not
trivial for most of the reimplemented routines) of the existing code and
extend it so that it can fit to our use case.
Otherwise I agree and I will rename the flag if we decide to keep it...
