You're really asking for hard mode, aren't you? :)

The versions emitted aren't the same, so you can use version ranges, e.g.:

# kf5 version
BuildRequires: (cmake(KPipeWire) >= 5.26 with cmake(KPipeWire) < 5.27.80)
# kf6 version
BuildRequires: cmake(KPipeWire) >= 5.27.80

This should not be a problem since the devel packages shouldn't be
co-installable in any circumstance.

Well, okay, this is an issue. You'll also run into this with KUserFeedback.
