@Lorimer @timk11 There was no particular reason that HTTP outcalls were not enabled on application subnets 4zbus and 2fq7c, it was just oversight that it was never enabled. This only recently became apparent because 4zbus became public and users noticed that outcalls were disabled.
I agree that the description of the proposal is rather succinct, and we could add more context in the future.
Since we definitely want HTTP outcalls available on all application subnets, DFINITY will vote to adopt 134382 and 134383.
