I think most of the new projects are still started with drupal 10 instead of 11. For this reason, in order to avoid upgrade problems with version 4 in the future, version 4 should be accessible for drupal 10. (it may be ^10.4 or higher)
You can currently install it with Composer, but you cannot enable it because it is not compatible with Drupal 10.
Or, the flexible_permissions & variationcache dependencies in group 3, which is already included in the core, should be removed with a new minor version as in version 4.

The reason v4 will only support D11 is because I plan to make use of the latest features available in D11. I can't make it support D10 if I'm using code that's not even in D10 to begin with.
I appreciate the request, but I cannot deliver on it due to above mentioned limitations.
