No.  That is totally outside the topic of this patch series.

I think I took them and merged them to 'master' today.

I saw that issue myself yesterday, too, I think, with a failed
attempt to fetch from one.  I do not think it is such a huge issue
in a sense that we can always say "don't do that", as cloning and
fetching only from the primary location is not something that would
make users feel unnatural.  After all, we sell this as "allowing
secondary checkout", meaning that it is perfectly OK for us to keep
secondaries second-class citizens compared to the primary one.  So
being able to fetch from and clone from is "nice to have".

One step at a time is perfectly fine.  We will be cautioning users
to avoid storing the only copy of their data in repositories that
employ this feature for a few releases until it matures by marking
it experimental exactly so that we can tweak external interfaces
like that incrementally.

Thanks.
