Sure, but then this becomes a bit of an irrelevant comment on a discussion of how WiFi 8 will focus on increasing reliability.

Your old devices won’t magically get more reliable because WiFi 8 comes out. You will benefit from this after it comes out by migrating to WiFi 8.

Meanwhile, you can benefit from existing reliability enhancements by upgrading to WiFi 6.

If your response to that is ‘I can’t use WiFi 6’ then presumably the putative benefits of WiFi 8 are even more remote.

Legacy clients force APs to accomodate them. Be it by using slower speeds with worse airtime consumption or by just disabling features that (can) make old clients misbehave.
