_STA has been required in SBBR since ver 1.0 (published 2016, with the 0.9 draft since 2014)
https://developer.arm.com/documentation/den0044/b/?lang=en
I do not have the history on why SBBR 1.0+ requires _STA, but it most likely has to do wit the Windows strong use case for it: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/device-management-namespace-objects#device-status-changes . Windows is a key OS targeted by SBBR.
