I use this approach in my repo:

https://github.com/gade01/repository.gad.../addon.xml

That's very useful for skins, where there is a different version for each Kodi version.

Thanks. Do you know if Kodi is planning to prevent the multiple separate directory method in the future?

Later versions of the official repo addon.xml only have one release in them
https://github.com/xbmc/xbmc/blob/master.../addon.xml
whereas before they allowed multiple versions
