It seems to me that there is not enough practical experience
with anything other than the current xz (+ ext4 + squashfs).
So run an experiment, such as: Before beta freeze, if a [rawhide]
compose starts on an odd-numbered day-of-month, then use xz.
If a compose starts on an even-numbered day, then use zstd -19 -b 1M.
At beta freeze, then reduce the frequency of changing from daily,
to weekly or less. Changing back-and-forth ought to affect only
a small number of packages such as: compose tool, dracut, ananconda.
Such an experiment should provide experience to better-inform a choice.
