LOL sure it is. (OK, my example was extreme, but come on this rule is also...)Except for the part where it's not remotely like that.
The entire point of Spell Versatility is for groups that play at a slower pace, so those players who make poor spell choices can swap them out sooner.
So, if your groups levels at a pace reasonable to the game's design, you should not need this rule. If you still use it when you don't need it, you are artificially boosting all known spell casters (sure, we've focused on Sorcerers due to their comparison to Wizards, but there are also Bards, Rangers, and Warlocks).
