But then again that's why in topology I made the distinction between
"standard defined" ("ST_" prefixed) and "postgis-proper" (unprefixed)
function. Postgis-proper you can decide on your own to drop any knob,
but standard-defined should follow the standard.

Minor thing: if you have 3d and want 2d output an additional call
to ST_Force2D would be more expensive than instructing the output
function about only considering the first 2 dimensions.
