Re: [webauthn] Can the private keys be used for other cryptographic operations? (#1595)

@certainlyNotHeisenberg Allowing a cryptographic key for several use/algorithms is a _bad idea_™ and has led to various _catastrophic failures_™ through unexpected protocol/algorithms interactions. As an example, this is why in both PGP and X.509 certification, signature, and authentication are three separate usages for keys.

In addition to all the specifications previously mentioned, there's also [Web API For Accessing Secure Element](https://globalplatform.github.io/WebApis-for-SE/doc/) that was intended for your use case, but ultimately wasn't kept by w3c due to the lack of interest at the time.
