Well I really am like you (no LH Group since beginning of March 2020) and moving more over to SkyTeam. But there, I am with Air France KLM, not OK (CSA Czech Airlines, right?) I hope CSA don't disappear, because with the AirEuropa takeover and the probable transformation of Alitalia into something else, SkyTeam is beginning to look a lot less interesting in Europe. Whereas LH Group is widespread with a lot of hubs.
About elite status extensions, AFKL offered an extension both last year and this year, along with the double XPs promotion. For me, personally anyway, they have handled the whole thing better than LH Group.
