Limited functionality for users after exceeding the user license limit

We have a local Confluence instance and experienced a very "hostile" limitation of fundamental functionality in the system after exceeding the 250 user limit that our license includes.

After we exceeded the limit to 255 users the functions to save a page (either after creating a pager or editing a page) were disabled for all current users and the attached error appeared.

I find this a very drastic consequence with a very negative affect towards the customer experience - instead of just throwing an error if user no. 251 is being created.

Hope you can find a more graceful solution to this.

Brgds.
