Thank you for your feedback. It is extremely unlikely your proposal
will be integrated.

Note that regardless of the "extractable" flag, Key objects support
the Structured Clone algorithm, and can thus be shared between origins
/ parties via postMessage.

This is a feature, not a bug.

As mentioned in another message, it is an explicit non-goal of this
API to "secure Javascript" independent of methods such as TLS, which
appears to be the motivation for this proposal.
