but they don't explicitly say they are raising the system voltages - it
wouldn't necessarily follow anyway, the regulated voltage could stay the
same but with a higher current draw being allowed.

Raising the voltage does seem an odd thing to do not least because they dropped
the voltage from 640V years ago citing power saving reasons (which sounds like
rubbish TBH , lower voltages are less efficient , not more).
