I think this will make for an excellent litmus test for companies that make wifi products. Is this a critical fix? No. Is it important, if not critical? Yes.

Some vendors aren't going to care about this in the least and won't offer any updates.

Some will only fix this in new and future devices.

And perhaps some will update all their devices going back several years.

Currently I buy used 802.11ac Airport Extremes for wireless for people because they're simple, they stay out of the way, and the last time there was a major update, Apple updated every Airport model all the way back to the Airport Express from 2008.

But I want to be able to buy new wifi devices, and how vendors handle this will inform me about which ones I'll buy going forward.
