Difficult to fix if exploited.

Can be patched beforehand.

I'm mad because one week ago I bought a brand new ryzen 3400g (ok, it probably sat in the warehouse for years) for my dad (he didn't need lots of power), i even didn't have time to take it out from the box, but they say "EOL, no patches for old shit" - while still patching mobile picasso cpus for laptops (same gen/process)

As far as im aware am4 boards are still getting bios updates? Don't know where you read that there would be no more patches? Asus and MSI seem to already have this patched

Official AMD website - for desktop only Ryzen 5000 or newer; for mobile only Ryzen 3000 or newer

The way they did the distinction is purely based on the time of put on sale. They patch Zen+ on mobile, they patch Zen2 on desktop only if it comes with integrated GPU, otherwise it needs to be zen3 or higher. If you already fixed the exploit on zen+ and Zen2 why not making available for everyone? Selling more CPUs I guess...

Hmmm... I have been eyeing a 5950x to upgrade from my 3800x (to turn this rig into a home server, full new gaming rig later).
