PSA: Please check that your Python 2 package doesn't have dependent packages before dropping it

[Randy Barlow]

Greetings!

I've been bitten twice in the past week by dependencies of my packages
dropping the Python 2 RPMs, presumably due to the Fedora 30 change[0].

Note that the change does state that the package should not be dropped
if other packages depend on them.

On that note, I do know how to check if other packages Require my
package:

$ dnf repoquery --whatrequires <something_my_package_provides>

How do I check if other packages BuildRequire my package? There doesn't
seem to be a --whatbuildrequires option on dnf's repoquery.
