To be honest, I expect this issue to be resolved maybe at full release?
Maybe so. But it's been known for a while and we keep referring to it as a bug or an issue when there's no evidence Larian consider it as such. Case in point, here are the threads I could find in the Suggestions & Feedback forum which mention Wizards learning any spell :

Keep in mind, this doesn't include the General or the Technical & Gameplay forums, though the topic has been brought up there as well.
Larian are aware. They've been aware from the first day of early access. It seems to be such an easy fix for an issue that's hung around so long that it may just be one of Larian's homebrews. After all, Larian haven't been shy about adding more power to existing classes.
Maybe they feel wizards need some help because enemies have more hp but their saving throws haven't been nerfed, or because all the spell ranges have been shortened. Maybe they don't want to explain spell lists to new players. Maybe they like the fact that players have a second option as a healer besides Shadowheart. They've actually said their data shows players want their spells to make fireworks rather than do boring stuff like Bless. So maybe they believe players don't care and in turn don't care themselves.
That's a lot of maybes and in truth I don't know what will happen. In the meantime, I find it fun to think about the in-game implications of Gale giving atheistic blessings to the party. Perhaps he's secretly a cleric of Mystra. Perhaps everyone in your party is secretly a cleric of Shar, and Shadowheart is just there for misdirection.
Or perhaps religions are fake and Gods are a lie. All hail the Absolute!
