Maybe. But what about add-ons the depend on Kodi original add-ons and those will ask for python latest edition. This might be a problem for that"....And this might mean the end of a big community that depended on KODI."
I've tested a K-19 fork a couple of times, just to see it function. I saw no potential benefit for us as we all use the product, so anyone who "upgrades" will only be wasting their time having to reinstall 18.9 - I don't think it signals the end of the Kodi community as we know it. There's no reason why we cannot go on indefinitely with 18.xx and survive nicely.
