I'm torn over this one. If you want to refer to local changes wouldn't
it make more sense just to totally override SRC_URI in cases like this,
then things are specific.

I'm worried that here, upstream revisions may just get ignored for
example with just a premirror copy being consulted and this wouldn't be
the expected behaviour a user would want.
