I like the spirit there, but as far as I can see the closest thing to a main, guiding principle for what they are trying to achieve with OneD&D is trying to impose lots of top-level order and hierarchies. There are now three spell lists; a taxonomic system of four catagories of classes, each with three classes; unified spellcasting rules; spells prepared equaling spell slots for no particular reason other than having a big dumb rule for all occasions; standardized class progression; and everywhere, always the unrelenting merciless proficiency bonus as the only number you ever need. Somehow I feel like me, or even a thousand mes telling them that the only coherent goal they seem to be pursuing is a fool's errand won't dissuade them from abandoning the only principle they seem to be designing around, which is big orderly systems wherever they can squeeze one in, everything else be damned.
