I think some zip implementations will store files in "raw" form if the
compressed version isn't smaller.    In any case, the real issue is to
find a reliable way for users to get a complete copy, and for many of
us, the usual mirroring by individual files is not straightforward.   Maybe
and on-the-fly tar (e.g., without compression) would be better.

It is a bit of a pain when different CTAN sites have different capabilities --
you end up with user A advising user B to do something that works for
the mirror site used by A but not the one used by B.

The other issue is more intelligent redirection to steer users away from
sites that have higher usage costs.   I think most people do try to follow
the advice to use non-root sites, but it does make sense for root
sites to run only the features used by non-root mirrors.

It might be interesting to look at the ratio between the bytes served to
CTAN non-root mirrors and the bytes served to users.
