I don't know if anyone has started implementing SHA-3 for PCRs.

AFIAK, no for SHA-3

Generally, TPM vendors do not implement optional features.  Since
applications cannot use them if they want interoperability, it
increases the TPM cost with no perceived benefit.

SHA-384, ECC NIST-P384, and RSA-3072 recently became mandatory.
