As long as docs.rs can't run with --all-features, I think that all practically relevant ones should be on -- and embedded-io and zeroize were missing (and thus only spottable by users who explicitly go into the dependency tree or into the source).

Both show up sensibly with doc_cfg:

I think this can skip the change log (as it has no effect on any build); if you disagree, the change log line I'd add is "Made embedded-io and zeroize implementations visible on docs.rs.".

Thanks!

I'll take a deeper look later, but I agree with skipping the changelog. This is not relevant for downstreams.
