I am for ECMA datestyle

it is there but just is not public, if I remember well

Theoretically some custom output/input transform routine can be very
interesting - for domains, for boolean type - but on second hand - the
usage of this feature is minimal and there is risk for less advanced
users - so ECMA datestyle is very adequate solution.
