RFC 2229 - closure migration suggestion bug?

[Mark-Simulacrum]

https://github.com/rust-lang/rust/pull/89075/files#r711626103 notes that our migrations suggested adding a let _ = &config; here. However, I would've expected that to not happen, because config is not a type with significant destructors (as far as I can tell). Maybe there's a bug here?

config has type LangString, which only contains Vec<String>, but I would expect that type to not trigger our migration tooling as it has trivial dtors.

Based on Zulip discussion it sounds like this is caused by not yet adding the insignificant dtor attributes to std, and @arora-aman is going to work on a PR to do that. We may consider backporting that.

I believe this is fixed by #89144 -- going to try to confirm locally.

Confirmed.
