RFC Failover url for fetches?

So when pushing it is possible to have multiple urls
(remote.<name>.url) configured.

When fetching only the first configured url is considered.
Would it make sense to allow multiple urls and
try them one by one until one works?

Background:

I wanted to fetch and had to fix a url of a repo
to point to a working mirror.

Thanks,
Stefan
