This is a process/decision-making question: I noticed that only
closeandnameare included forDedicatedWorkerGlobalScope, why only those two? Is there something unique about them that the other properties don't have?There was a problem hiding this comment.

In this particular case, it seems to be because the other BCD keys under api.DedicatedWorkerGlobalScope are already assigned to other features.
If you open https://web-platform-dx.github.io/web-features-explorer/ids/, you'll see the entire list of features, together with their BCD keys. On that page, you can do a search for "api.DedicatedWorkerGlobalScope".
You'll see that api.DedicatedWorkerGlobalScope.message_event and api.DedicatedWorkerGlobalScope.postMessage, for example, are already part of the postmessage feature.
Currently, in web-features, a given BCD key can only be part of one feature at most. This is something we might change in the future.
You're asking a good question though. I don't think there's a super clear way to answer whether those BCD keys should be in postmessage, or in dedicated-workers.
