I agree that those two leisure keys are somewhat odd, as they appear to be based on a legal designation rather than physical characteristics. However, that's probably not the full story in the UK, as they're likely to be used for patches of land that have the appearance of a typical common or village green, and thus would be recognised as such by most residents, even if legally they're not. The "village green" and "common" terms can be thought of as comparable to other names for open spaces such as "recreation ground" and "park", but distinct from a UK point of view. Some legal village greens and commons could well be "recreation grounds" and some may be "parks" but many will not be either in the British English usage sense. To capture the legal designation of patches of land, I would recommend using the designation=* key, with something like designation=common_land and designation=village_green. (However, we probably wouldn't want to automagically add these tags to all UK leisure=common and leisure=village_green objects, as some of the uses may be based on appearance and not legal status.) Access tags can also be added to describe access rights. But in addition to this, we'd need something to capture the physical state / utility of the area. Often neither leisure=recreation ground nor leisure=park will fit the bill. If not, then natural=heath, natural=grassland, or natural=meadow may fit the bill for commons, but it would be a shame if we didn't have something specific for village green type areas of maintained grass. In conclusion, I think there are reasonable arguments in favour or replacing leisure=common with more appropriate tags to describe the legal status, physical condition and access rights. But I'm not sure about village_green, as there's a physical/utility aspect captured there that I think should be maintained, and I'm not sure that there's an alternative tagging available at the moment.
