https://github.com/privacycg/storage-access/pull/138 makes it so that SAA is based on Permissions in the spec. I'm not 100% sure how that maps to WebKit internals, but we would like to expose these permissions through the Permissions API as well, for developer utility. This will be done in Chrome in https://bugs.chromium.org/p/chromium/issues/detail?id=1401266 and is tracked for Firefox in https://bugzilla.mozilla.org/show_bug.cgi?id=1805860
