Note: I assume this is due to the same buggy assumption element X is using of having unsinged devices. Element (as in the product) seems to be forgetting that there exist developers in their customerbase which by nature of matrix will always have unverified devices since not even all clients can do that.

As long as this is not possible to happen network wide, I do consider this behaviour both broken and actively hostile to their userbase. Even worse there exist devices which are unsigned due to element X...

Ok turns out there is in labs a hidden "disable" button for globally disabling it...
