Even more important: I hope Wifi 8 makes all the good stuff MANDATORY even if it's expensive!

For example, Wifi 7 doesn't make actually useful MLO mandatory. So most wifi router manufacturers - even Ubiquiti - don't implement it! What's the point of adding something to the standard if it's optional.

Ideally, the standards body should make expensive stuff mandatory- then prices will come down as soon as everyone is building it, due to economics of scale.
