Err, no, bulk of the computer industry is out of step with sanity:

Not to mention that although not infallible, ECC also offers an additional
layer of defence against rowhammer attacks.

Yes, ECC memory will cost 25% more, there's no way around that as it
requires 10 bits of memory for every 8 bits of data.
As for motherboards, you will find that just about every AMD CPU supports
ECC, and most motherboards for AMD CPUs also support it.

Lack of ECC support is very much a desktop grade Intel thing. AMD's desktop
CPUs do support ECC, even if it isn't widely advertised.
