Wouldn't you be better off asking the upstream developers of XZ this
question or even better, downloading these versions and checking for
yourself? After all, no one is obligated to do this work for you.

Are you talking about the compressed stream of data that openssh can use
(if enabled), or do you mean the compressed binary package that Debian
makes? For questions about software functionality again I expect you
would be best off asking the upstream openssh developers.
As far as I am aware openssh only uses a form of zlib compression and it
is not commonly used.

This is a good question for Debian since Debian is doing the packaging.
I'm not sure of the answer. I mean, there are certain Debian build
servers ("buildds") that compile the software and compress the packages
but I am unsure whether they use the xz binary from the same release
they are packaging for (e.g. Debian 13 "trixie" xz when making a package
for Debian 13), or the xz from the buildd host itself.
I don't think there is going to be anything tracking brand new releases
of xz to use for this purpose though.
A more knowledgeable person is likely to answer this bit. 😀

For all but the packaging questions, definitive answers would need to
come from the software authors.
Thanks,
