Note that some of the Constrain* types you listed are not dictionaries in the spec, just incorrectly claimed to be dictionaries on MDN. (They should still be removed IMHO.)

Another enum spotted in #10784: XRSessionMode

[foolip]

These are the *Init.json files we all, all dictionaries:

api/MutationObserverInit.json
api/RTCIceCandidateInit.json
api/VRLayerInit.json
api/DOMPointInit.json
api/RTCTrackEventInit.json
api/RTCRtpTransceiverInit.json

I've found some other dictionaries in our BCD by searching for the word "dictionary" in the MDN content, as well as greping the files for "options", "configuration", "parameters", etc. There are...a lot of dictionaries still in BCD, it looks like.

I've updated the issue to turn it into a checklist of what we have left to remove and added all of the additional problematic files we've found. I'm also pinning this issue since it's an important goal and even helps bring our real value percentage up some!

I believe https://developer.mozilla.org/en-US/docs/Web/API/Transferable is also a non-interface page / BCD data.

Good catch, thanks @Elchi3! Yeah, this looks like something we can remove. I've added it to the list!
