It doesn't take much longer, because for normal pkg updates, it would only
examine the latest pkg release. It should take into account obsolete
binary pkgs from the previous compose, however. Only *that* would help
with detecting incorrect/missing "Obsoletes" tags (which is something my
modified repoclosure handles, because in Extras we've had up to two pkg
releases in the repo). On the contrary, the Rawhide report is like a fresh
install of only the latest pkg releases, and one can only hope that there
are enough testers who find and report the additional update/upgrade
