without the SECTION, spec-cleaner and the equivalent obs service move the boolean dependency away from the comment and away from the python3-qt5-devel BR.

See https://build.opensuse.org/package/show/home:bnavigator:pyqt:dependers/krita?rev=11

When the move to the sip-devel metapackage is complete, we will have:

• python-sip-devel depending on the selected default (python-sip6-devel)
• python-sip4-devel
  • has /usr/bin/sip
  • has independent namespace, so does not conflict.
• python-sip5-devel
  • has /usr/bin/sip5. Upstream always marked this transition helper as deprecated.
  • provides and conflicts on python-sip-impl
• python-sip6-devel
  • only has the new style commands, sip-build and co.
  • provides and conflicts on python-sip-impl

No need to introduce extra file providers, one can do BuildRequires: python3-sip5-devel then.

But it is not in place yet, we are still waiting for the creation of devel:languages:python:pyqt. Submitting python-sip6-devel to KDE:Qt5 would be wrong IMHO.

/usr/bin/sip and /usr/bin/sip5 are update-alternative controlled and provided by multiple python flavor packages (python36, python38, soon python39 ...). I think introducing a file provides tag, could create problems with the resolution to the right python flavor. Specifying primary python3-sip(5)?-devel as it is right now, does the right thing here.

Good point. I was not aware, that you also want to support Leap 15.2 without updated PyQt5 and SIP v5 packages.

Let me try to come up with an even more complicated boolean dependency.

Turns out, a simple BuildConflicts: python3-sip-devel >= 6 is the better solution.
