I'm talking in general, why not use the same improved compression for
all!

Because createrepo wants to keep backward compatibility?

Wait a minute, is that what you're saying someone from EL4 poking around rawhide repo? :)
Yeah, I see how it is convenient to hold backward compatibility when you need it.

For things that can use xz, they only download the xz files.
For older things that cannot, they can download the gz files.

Old things have to evolve.
Old things should be upgraded.
We are talking about the rawhide repo, right. :)

If your package manager does support xz repodata, you only ever get
those. The mirrors keeping a few trivial sized .gz files doesn't affect
you in any way, and allows people with older tools to still look at the
repos.

Again, these old things! :)

The exception in your list is the repomd.xml file. This file is vastly
the most accessed one in repodata. Compressing it with xz (or gz) would
be largely pointless since it's so small already and it would make
everyone have to uncompress it lots and lots of times.

Around this we agree. :)

Although you are not commented delta repodata.
Scary little thing, isn't it. :)
