The links you posted were up before but now they're broken. Do you have updated links (and maybe one for the 980080 WLC also) and do you know when we can expect 17.3 for switches and WLC?
I'd guess, 17.3 should earn MD-status.
But i can't find any official "Support Timeline" Documentation mentioning IOS-XE 17 - if everything proceeds as 16.9/16.12 did in the past...
Of course official documentation would be highly appreciated.
