My feeling is that truly private, end-to-end encryption using the
WebCrypto API (or indeed any JS crypto library) is only possible if
implemented in an open-source browser extension, such as Cryptocat. As
far as I can tell, it is not possible in a web app using the WebCrypto

Probably, but some reasonably simple standards should be possible. For
example, encrypting/decrypting text and encrypting/decrypting files
look like two relatively simple and fairly general use cases.
