Not really, at least to me.
It's internal to SK (also, in my personal experience all flights credited, and didn't take too much of an effort, although, granted, I may have been lucky).
I expect whatever issues remain to be solved sometime in the next several months.
What I care about more atm. is the external benefits - lounge access and extra checked bags primarily.
