-#   IMPORTANT: When bootstrapping, it's very likely python-pip-wheel is
-#   not available. Turn off the rpmwheels bcond until
-#   python-pip is built with a wheel to get around the issue.
+# Bootstrap enabled:
+# - disables regen-all with the same Python version
+# - disables dependency on python3-rpm-generators if we build with main_python
+# - disables rpmwheels, optimizations and tests by default
