Would you have preferred if I used a different superlative? I still
consider 30% less to be significant, especially because DNF5 processes
metadata in parallel which makes things seem faster, whether perceived
or real. And yes, the other improvements are good as well, but end
users focus on speed. See: constant discussions about how to make DNF4
faster (including enabling fastestmirror which can make things slower)
or perception that it is slower because it processes metadata at a
different stage than apt for example.
