First. Yes Intel has been stable for many years in the past. UNTIL Alter lake and later( 12xx,13xx,,14xx series) and thats because those are all factory overclocked to some degree. Intel had to, to keep the crown for most things.
As to your suggestions on Overclocking, here is the root of the issue. 99% or more of all users, buy or assemble their PC, then run it. They don't know how or care to overclock. But in the case of these, thats already a factory "feature". So 99% of all users see a problem with these under heavy sustained load. (percent having the problem was using those who don't adjust BIOS, not the actual number of users)
