I'm not convinced this is what the game is doing yet, but maybe. We'll see in a couple days.
It does make me wonder if that's why the wizard was able to scribe cleric scrolls in earlier patches. Perhaps it was in as a test to see what would happen if the wizard suddenly had access to a bunch of cleric spells. I never found that to be overly powerful. As an above poster commented, you still have the same number of spell slots and have to make choices.

Still. I'm not convinced the game is doing this, largely because it seems to make some choices irrelevant.
I'm not too concerned about a wizard dipping one level into a cleric for access to a much larger spell list.
But what about a sorcerer that dips into a level of wizard to be able to scribe scrolls? Now the sorcerer has all the sorcerer benefits along with the versatility of the wizard, right? Meta magic and scribe scroll to get all the spells. That seems like an odd direction to me.
