It could, but when you look at clauses 5 and 6 of BS 5733

In fact the product contains 4 13A sockets and 2 USB powered sockets in one
enclosure. They are of two different products put together for customer
convenience.

Ground/earth continuity is extremely important for electrical medical
equipment, at least in part because sedated or comatose patients can lack a
"let-go" reflex. Clear plugs presumably allow users to periodically visually
check the robustness of the conductor/pin connection.

I think so, but don't count on it.
I think I agree with that, although it would probably not be acceptable for
aesthetic reasons in the consumer market!
Also, in the early days (1980s) of moulded BS1363 plugs there were a number
