One request: the use of static method syntax for all three methods, when
only 2 are static, is pretty confusing. It'd be ideal to update the
explainer and ChromeStatus entry to make it clearer which methods are
static methods (PublicKeyCredential.parseCreationOptionsFromJSON(),
PublicKeyCredential.parseRequestOptionsFromJSON()) and which methods are
instance methods (PublicKeyCredential.prototype.toJSON()).

Regarding Firefox's position: I notice they are not passing the web
platform tests: 1
<https://wpt.fyi/results/webauthn/public-key-credential-creation-options-from-json.https.window.html?label=experimental&label=master&aligned>,
2
<https://wpt.fyi/results/webauthn/public-key-credential-request-options-from-json.https.window.html?label=experimental&label=master&aligned>.
Are you sure you have their position accurately recorded?
