I am afraid having to install Guix and run 'guix publish' will be a
major obstacle for most mirror sites, especially when their maintainers
have no previous experience with Guix and have no interest in learning a
new software and do not want to pollute their server with an unknown
software and do not want to increase maintenance burden. This is the
simplest solution on our side, but a complex solution on mirror site
maintainers' side.

I guess a complex Nginx URL rewrite rule might also convert the URL into
real filename in the cache.  Can anyone familiar with Nginx explain?
