> That technically breaks ARM spec

It does not (or it wouldn't be there) and they aren't the only ARM vendor with TSO (Fujitsu also does it.)

Optionally enabling it does break the ARM spec.

Their cores break the ARM spec in other ways too. Added instructions for AMX, new guard privilege modes, HCR_EL2.E2H can't be disabled, GPRs are clobbered on WFI, etc.
