Right. Do you think we should backport this to stretch ? I would be
inclined to say "no" because of the compatibility risk, but it seems
arguable to me.
IDK who else might be using ext:. As for dgit, which is where I
noticed this, the breakage is in the dgit _test suite_. dgit itself
does not use ext:. I have no idea whether that's usefully indicative
of other callers' situations.

Right. This is why I'm not asking for this change to be reverted.

If I emailed you from an address @fyvzl.net or @evade.org.uk, that is
a private address which bypasses my fierce spamfilter.
