IIRC it's still being slowly implemented, as slowly as things are made mandatory - because any telecoms that can make money by forwarding fraudster calls to other telecoms don't want to support it.
I believe SHAKEN/STIR was mandated only for calls originating from within the US, however, most of these fraud calls are originating over VOIP (or SIP) from outside the US.

whatever happened to SHAKEN/STIR and why didn't that fix everything like people said it would?
