Swift being maintained by the open source community is an illusion. The community was very against function builders. Apple went ahead and did it anyway because they needed it for SwiftUI. The open source community just provides discussion, and Apple gets its way either way.

Scanning the multiple review threads, that doesn't appear to be the case. According to the acceptance post, the community was overall positive about the feature but expressed concerns over the attribute naming, which was renamed in response.
