hm, I think I understand what you're trying to differentiate there, but I would not do it that way. we have two orthogonal authenticator characteristics: [attachment modality](https://w3c.github.io/webauthn/#attachment), and [transport](https://w3c.github.io/webauthn/#transport).  

attachment modality of `cross-platform` matches your attempted use of the term "removable" I am guessing. 

AFAIK, a [platform authnr](https://w3c.github.io/webauthn/#platform-authenticators) (i.e., non-removable) might actually employ one of the transports, e.g. USB, rather than something else that the proposed "internal" platform-specific value is intended to address (i suppose a [platform authnr](https://w3c.github.io/webauthn/#platform-authenticators) could use _any_ of the transports, but having a one using BLE or NFC offhand seems silly).

I think the Note in section [5.4.5 Authenticator Attachment enumeration](https://w3c.github.io/webauthn/#attachment) already largely addresses what you are attempting to hint at with the use of "removable".
