It makes alot less sense now with SSD's being as fast as they are largely llimiting how long a loading screen will be.
I played Bayonetta for the first time a few months ago on my steam deck, and during loading times you were able to practice combos and stuff. Unfortunately it only lasted for a split second since it loads so fast from the SSD, I'm guessing it's original release on console disc allowed players a bit more time to try it while it was loading from the disc.
