Can you provide a link to this?

It's actually possible to pass --whatrequires mutliple times with all of
the dependencies, instead of running multiple queries. e.g.:

sudo dnf repoquery --whatrequires pcre --whatrequires pcre-cpp --whatrequires pcre-devel --whatrequires pcre-static --whatrequires pcre-tools --whatrequires pcre-utf16 --repo=rawhide{,-source} -q | grep '\.src$' | sort | uniq

This is quite a bit faster. I only just recently learned this, so I
thought I'd pass it on :).
