It is, they train on conditions almost identical to the ISS for months before new astronauts/cosmonauts go up.
Besides, they have plenty of research information on that anyway, and it's not like when we have permenant space stations they'll actually have weightlessness. Time and money should be made on pratical and applied technology, not garbage research.
how would you exactly maintain prolonged weightlessness on earth?
