I agree with all of the above!
As much as I despise my old art, I sometimes cherish it too. There are things I did with my old style that I've sorta put away with the new (gray/softer-looking lineart, more details/objects in background that add to story/atmosphere, the "fullness" of a page vs "refined/clean mobile format"), and I'm thinking of slowly incorporating some of the older aspects in the newer eps (more detail in world/bg, but with softer lineart, gradual shading vs cel->maybe, I'm experimenting...).
If I had gone back and redone the old pages, I wouldn't be able to see how far I've gotten. My only one regret is that I did so many pages before uploading (almost a year's worth), before I'd put my cleaner style somewhere in the middle to separate/add-in events in a better order/fill in story details, etc.
But in the end, despite the roughness and style whiplashes, I'm leaving those pages alone. It would be a huge waste of my time and effort. I've got other stories to tell, can't be weighed down with this one (I still love it to pieces, tho).
I had said I'd redo them for my one year anniv, but as of now, that's not happening. (sorry, readers, hope you understand!)
