Attestation was most definitely removed from Apple's implementation.
For Google, there's still a (relatively obscure) way to get a non-synchronizing/non-discoverable credential (which is then by definition not a passkey!), which then supports attestation, but that's Chrome+Android specific and wouldn't work on e.g. Chrome on Windows or macOS.
