Assumption.
For aircraft/vehicles crossing, providing that they are in sight of the ATCO and workload is such that attention is not likely to be diverted elsewhere, I don't see why a vacated call is going to make operations any safer and is just unnecessary RT imo
How does the vehicle driver know that the vehicle is in sight of the ATCO?
Strips are procedural, actioned by R/T procedures.
Visual surveillance still requires R/T confirmation, as your 'free ranging' example demonstrates.
Consider low vis when visual confirmation not available. R/T will be needed then.
