From w3c/webrtc-pc#275 (comment)

tl;dr: This avoids the temptation to write "snowball" dictionaries for the purpose of return values.

Member name collisions not from inheritance would be a compiler error.

Additional potential (mis?)use-case w3c/mediacapture-main#211 (comment)

The common base requirement is artificial I suppose.

Member name collisions don't have to be a compiler error either, really. As long as the caller can tell what sort of dictionary got returned...
