Sorry for the delay.
I am worried about https://github.com/sindresorhus/meow/releases/tag/v9.0.0 breaking changes.
The kebab parameter change.
I wonder if this will break legacy generators.

[gyz0072004]

I got your concern. Then do we have any plan to migrate yo to pure ESM package as a major release? I think some yeoman has done the migration.

I'm closing the PR for now.

Last yo major version had legacy generator issues, so I am very careful about yo changes to avoid angry reactions.
yo and yeoman-enviroment have quite unique use case. The must have almost 0 breaking changes forever to don't break old generators. They are engines instead of dependencies.

We use a custom cli in JHipster and yeoman-environment has a cli itself (yoe).
So I would say that another cli (@yeoman/cli) based on yeoman-environment cli support is the easiest way to move forward but as I've said we use custom cli, so I will not lead the task myself.
