Hmm, it's what I got from unpacking the CPIO of the rpm package, but looking at
the specfile of 0.54, it requires python%{python3_version}, which resolves to
3.8 on Fedora but would resolve to 3.6 on CentOS-8, so you're right. The
exact version doesn't really matter, what should matter in the email is the
overall idea to actually try pushing for a more modern meson.
