none of the Asus z370 ones have it, and almost none of the z270 had it either.

Despite Ryzen AMD is still negligible as far as market share goes.

AMD's overall marketshare is still low because of near-zero laptop or OEM penetration but their share of retail CPU sales (i.e. the only people that buy motherboards) is nearly 50% according to every recent sales report I've seen.

edit: Also they do have a Z370 board with PS/2, the ROG STRIX Z370-G GAMING.

AMD isn’t anywhere near 50% market share in overall sales when it comes to enthusiast hardware.

It looks like you got the only mono from Asus that comes with a PS/2 port other than the Apex: https://www.anandtech.com/show/11860/z370-motherboards-asus-...

ASUS has literally dozens of current motherboards with PS/2 ports, including 5 Z370 models. I really have no idea where you get the idea that they "dropped it completely".

Geizhals lists 63 Z370 mainboards for me. 48 of those have PS/2. That's 76 %.
