One use case is that we're using reusable workflows to run in a specific runner group (with extra permissions) and nothing else can run in that. However, whenever we release a new version of that workflow, we have to add that specific ref to the whitelist and ultimately that list will just grow.

We do already have the capability of whitelisting actions with wildcards as reference. https://docs.github.com/en/organizations/managing-organization-settings/disabling-or-limiting-github-actions-for-your-organization so why not apply the same rules to the allowed workflows.
