What is the global environment for?

Hi, using my hatch environment extension, I ran into an usability issue: there are extensions that use the global Python environment such ruff and ty.

When setting a workspace environment, these extensions still use the global env, for which there is no clear indicator in the UI. How should this be fixed:

• should my extension just also set the global environment whenever setting a project-scoped environment?
• should these extensions be changed so they stop using api.environments.onDidChangeActiveEnvironmentPath, which seems to track the global environment?

Maybe I just don’t really know what the 'global' scope is for … any guidance?
