I must be missing something here. Coming back to the original question – why would anyone expect to be allowed to spend longer charging than anyone else because they are disabled? Would it improve their mobility?
I think a destination charger (7kW) provider should consider removing any time limitations for blue badge users. The idea of having to get back to the car and then move it into a different space may not prove to be easy or realistic. And then there is the usual argument about how long it takes to do stuff when you are at your destination.
I agree with you at an MSA. Take what you need and jog on asap.
