With the addition of two more lines of polymorph spells in Ultimate Wilderness, namely Fey Form and Ooze Form, is it reasonable that spells like Greater Polymorph (Or Polymorph Any Object) and Shapechange get updated to include all the various form-taking polymorph spells?
Considering they don't update things like Summon Monster when a new Bestiary comes out, it is unlikely. You are free to do whatever you wan in your own home game, of course.
