Warlock with full list of Wizard spells !!!

I found out today that if you make a lvl 12 Wizard, learn all the spells you need from scrolls and THEN respec into Warlock with a 1 lvl Wizard dip, you get to use up to lvl 5 wizard spells with your refreshable Warlock spellslots!!!!!!!

That is all.

EDIT: my comments keep getting downvoted, why? Was this known already?
