Zipping in to say oh yes! So agree! In fact, I wrote a paper on how GRASS was a feminist epic response to DUNE, and at the time, it was incredible (I've been a fan of Tepper's since her first work began being published, and at that time, her stuff was radical.). I also loved the planet GRASS (much more than DUNE), and yes, Marjorie Westriding is a bit limited in my eyes, now, but at the time! (Her first publications, the GAME series, came out in 1983!).
