It looks like few people only are using Wifi 7 for now. Maybe they are going to include it in the next generation when more people will use it.
Machines can last and be used for years, and it would be a presumably very simple way to 'future proof' things.
And though the IEEE spec hasn't officially been ratified as I type this, it is set to be by the end of 2024. Network vendors are also shipping APs with the functionality, so in coming years we'll see a larger and larger infrastructure footprint going forward.
