It must surely follow that an observer independent description is

Wrong, it seems Newtonian coordinates are preferred (mostly
because they simplify certain specific problems), but the least
complicated _general_ solution does not use Newtonian coordinates,
but does need the tools to translate to and from Newtonian coordinates
and concepts.
