It depends to who you're referring... is it better for those waiting for new mods? Yeah, sure. It is better for him? Not really, since he wants to do it his way and wants to fix it.
Nexus is already flooded with thousands of mods similar to eachother... all these witcher lore-friendly, eyes, reshades, retextures of stuff and so on. That's good in my eyes since we have more choices!
While having completely new mods is amazing (and I agree with you there) you gotta think that he might be doing this just for the sake of improving his modding skills or for whatever reason he's doing. The community doesn't really matter when he's the one doing the mod. Pretty sure he will carry on his way till he finds a way to fix it and then I'm pretty sure he will focus on other stuff, probably those (really good btw) e3 exploration animations.
