It's needed for archive mirroring, where you register two copies of
the same archive in different locations, e.g. foo@bar--xyz and
foo@bar--xyz-MIRROR, then use `tla archive-mirror foo@bar--xyz
foo@bar--xyz-MIRROR` to copy from one location to another.

Some other operations (e.g. abrowse) also work correctly on mirrors
like this.

Unfortunately, a lot of tla commands don't work properly in this way
and I don't think it's documented anywhere which do and which don't.
It's a tla bug that it doesn't even complain about this.

IIRC some people were suggesting a while ago to allow multiple
locations to be registered for a given archive (to allow mirroring)
and only allowing archives to be registered with the correct name.
I'm not sure whatever became of this idea.
