Hi John,

Another belated reply, I'm afraid - I'm doing a bit of catching up after a
hectic December.

I think your suggestion makes a lot of sense i.e. returning another
"stub_everything" that has knowledge of its provenance.

The ticket [1] has now moved to Lighthouse, but I'll add a comment to
reflect your suggestion.

Cheers, James.
