Re: [PATCH 0/2] fast-import: add mode to re-sign invalid commit signatures

If you're _not_ going to implement that in interoperability mode, then
I'd rather you just die in that case so that the test fails and then I
or someone else will fix it.  `extensions.compatObjectFormat` is
presently experimental and the data formats will change, so nobody
should be relying on it working as it stands right now.  There _will_ be
more compatibility breakage coming in future series, for instance.

It sounds like a very prudent thing to do to die as unsupported.
Thanks!

I _would_ recommend regardless that you add a test like in t7004's
"signed tag with embedded PGP message" if you apply this to tags as well
as commits.  That requires a special case in our interoperability code
(since it normally converts things that look like signatures, but when
we're _generating_ a tag, we don't want to do that since there are no
signatures yet) and making sure we do the same thing in fast-import will
avoid corruption in our conversions.
