I do not see why such a "oh, the repository at $URL1 seems to be
down, but we know $URL2 serves the equivalent information, so let's
go there instead" feature has to be limited to submodule use case.

So, no, I do not think a contribution to add mirror repositories as
alternate submodule sources should be considered for inclusion, as
it artificially limits usefulness of the feature.  A feature to add
mirror repositories as alternate sources might be worth considering,
though.
