It would make things simpler. Simple enough that some people would
reject your proposal as
incomplete. Others would prefer the split and reject a proposal that
tried to handle both
topics at once.
On topic: I think it is important that information can be added by
looking at the device. This means that in my opinion
/socket:cee_blue= /and/socket:cee_red= /should be valid tags. The
amperes, if known, could be added with socket:[type]:current= like
suggested in the wiki.
But socket=* is defined for use with amenity=charging_station. That
can be changed, but would
probably require a proposal and a vote. Maybe not, because from what
little I've seen on the
subject, electric cars often have cables that allow them to be hooked
up to domestic power
feeds and maybe even camp site hook-ups. Socket=* already defines
BS1363 sockets (UK
domestic power) so adding others may be OK without requiring proposals
and votes.
Even so, I'm not happy with socket=* because "socket" is an ambiguous
term which may refer
to either female contacts (regardless of whether the connector is
fixed or free) or a fixed
connector (regardless of whether the contacts are male or female).
For those of the "free
connector is a plug" persuasion, enjoy

The connector for a car charging station (or an amenity=power_supply),
even if fixed, could
have shrouded male contacts. It would be better to use connector=*
than socket=* and
encourage migration.
Connectors too are not necessary fixed.
When mapped in OSM they are fixed by the location given. So I see no
problem with OSM defining the socket/connector as being in a fixed
location.
Except, of course, there are other ways of transmitting power, so
electrical_connector=*, with electrical_connector:type, and all the
other socket:type migrated,
plus electrical_connector:contact=male|female. All of which is too
sensible to ever happen. :)
Currents: Installations here do not use connectors that have a higher
current capacity than the circuit can supply.
I think that is in the AS wiring rules, and those are legal requirements.
This helps to stop circuits being overloaded.
While this may not be the case in some places, so OSM will need to
allow for it.
