If I'm not misunderstanding things, that key never went through a proposal
process.  But it looks
like a reasonable foundation and has been used in the wild.  I suggest we
try to fix up any
problems and do something with it, rather than re-invent the wheel.  Also
incorporate the USB
idea from its talk page - some cafes/airport lounges/trains/buses now offer
USB sockets.

I'm in three minds about that.  There's no sense in power_supply=no +
power_supply:socket_type=europlug.  Having power_supply=yes indicates that
the socket
type is unknown, having power_supply=europlug is all that's needed.  OTOH,
power_supply:socket_type is consistent with the tags for power, voltage and
frequency.  On
the gripping hand, the recent proposal here was for amenity=power_supply,
so power_supply=
yes|no becomes unnecessary.

It wouldn't be impossible to add all the wikipedia socket types to it.  And
would be a good idea.

The question is what formal process (if any) do we use to amend the draft
and take it to a vote.
