Did this regress in #124382? cc @petrochenkov

Specifically 7517a4f seems suspicious due to title alone, didn't look into it much though.

This was reported by one of the affected crate authors in #124535.

WG-prioritization assigning priority (Zulip discussion).

Since these crates regressed, it could probably be good to keep this on the radar (release in 15 days)

@rustbot label -I-prioritize +P-high

[petrochenkov]

I plan to fix it later this week (#124535 is assigned to me).
