On my machine cargo build takes 11.5 seconds before and 8.5 seconds after.

Hey, is it possible that this change screwed up builds of some dependent packages because it changes the way cargo resolves and merges features of dependencies?

It looks some crates (including bitflags, serde_json) implicitly depended on the "serde/derive" feature to be enabled, and this worked, because trybuild pulled in that feature, but no longer works, because trybuild no longer uses the "serde/derive" feature.
