Isn't this going to impact the use of pristine-tar?
https://packages.debian.org/sid/pristine-tar

https://github.com/pah/pristine-tar/blob/master/pristine-xz states that:

The approach used to regenerate the original xz file is to figure out
how it was produced -- what compression level was used, etc. Currently
support is poor for xz files produced with unusual compression options.
