As long as the mirrors provide the files at the current address (via
hardlinks, redirects or rewrite magic doesn't matter) I don't see an
issue from the portage side, of course if the mirror script uses
portage we have to take a look at that. But such a change would be an
internal infra thing more or less.
I'm very opposed however to any client side changes, not only for
transitioning issues but also as this would require special casing code
for gentoo mirrors, both in mirror:// and GENTOO_MIRRORS handling, and
as TGL has mentioned there are some cases where we can't be sure if we
have a mirror with this new or a "traditional" structure. If at all
this would need a generic solution, something that's probably a bit too
complex for a (minor?) performance issue.

In the beginning, there was nothing. And God said, 'Let there be
Light.' And there was still nothing, but you could see a bit better.
