Should migrate be handling nursery promotions?

[lgarron]

It looks like Biome promoted useGlobalThis from the nursery in 2.5: #10510

This is a great change! However, I have a config used by almost all my JS repos that is broken by this. I tried running the migrate subcommand and it didn't move useGlobalThis from nursery to style (or make any other changes). Looks like I'm in for a whole bunch of manual combing through repos.

The subcommand description says:

Updates the configuration when there are breaking changes.

It seems that either:

• Nursery promotions are not considered breaking changes, even if there is no transitional deprecation period for the old config location.
• I should file a bug about the migrate command.

I haven't been able to find an answer to this. Could I ask the maintainers to clarify?

Migrate should cover nursery promotions.

It was an oversight. Feel free to send a PR. The file is called rule_mover.rs and it's very simple
