Well, the reworks are necessary in more than one way. Hint: The rig system is needed for the game to stay as small as possible to stay viable for mobile uses, which grew significantly in the last year, it's needed for added flexibility later on, it finally provides one common art/animation standard, etc.
Else, DC said he talked about alternatives with his staff, but decided against it, for the reasons I mentioned. He wants to focus on the game and not bother with anything around it. If you don't agree with it, that's fine, but don't expect anything to change anytime soon.
PS: If your only source is some guy who was hurt by patreon and is now obviously obessed with them, you may reconsider a bit.
