Isn't that just a standard RPM dep solving problem, at least for stuff inside Fedora repos or well known 3rd party add-on repos ? Take the minimal build root and run 'dnf install wine' and watch what is installed to get transitive runtime deps. Similarly use 'dnf builddep wine' to get transitive build deps. We can see the latter from koji logs https://kojipkgs.fedoraproject.org/packages/wine/7.2/1.fc37/data/logs/i686/root.log It is a surprisingly large set - 522 packages as build deps, but none the less this is automated info, instead of having package maintainers try to figure out if their package is actually still needed or not.
