I knew that "passkey" had grown to refer to a set of different things. I can't say this upsets me, as it does sound like progress over the old status quo. Still, is confusing for those of us that bought in at the beginning.
In particular, they distinguish between "copyable" and "hardware-bound" passkeys. They're both passkeys, and can be used wherever passkeys are supported, but only the "hardware-bound" passkeys support attestation.
There should be a different standardized term used for hardware bound keys. So users wont get confused.
