It's probably also everything that is accidentally overlooked during the shoot. Previously you would hat a different take, perhaps, or live with the goof. Now you can just offload that to post-production.

But probably also a question if how expensive filming days are with the whole crew vs. how expensive VFX artists are. The latter work is also highly parallelizable.

It’s probably a good ol perfectly rational slippery slope. Fixing a minor mistake or two in post is absolutely the best choice for everyone. Each additional fix is not worth a reshoot either. But slip too far and the product suffers.
