The Default Value Set in the Variable Library poses a risk.

The Default Value Set will silently apply values when no explicit value set has been selected for a Test or Prod workspace.

There is no warning if we forget to select a value set in Test and Prod. This can result in deployments incorrectly using Dev values in Test and Prod - without any warning.

Fabric should allow us to disable or remove the Default Value Set, and require every workspace to explicitly select a value set.

This can cause the same problem of exposing DEV or TEST data in PROD for example.

See the following similar, but different use case IDEA. Shortcuts with invalid paths when a variable set is selected should ERROR not default to previous va...
