these are actually the correct main flags in regard to sports and the french flag should go into the alt folder for them. it’s actually in practice for sports events to use the regional flags in many instances, as this is who they represent, not the entirety of france.
the french flag is official, as they’re part of france, but they are not france (which is the sum of all french territories). bit counterintuitive, but that’s how it should be handled. same with england, scotland et al - part of britain/uk, but each one of them alone is not the uk.
