The spellcasting compromise actually isn't new. Look at Reserve Feats. Or Arcana Evolved before that (the 25th-level spellcaster still has a limited no. of 9th-level spell slots but has virtually unlimited uses of 1st and 2nd-level). We're not asking for a Fireball ability at will at 10th-level. At 10th-level, I'd gladly give the Wizard unlimited uses of say, Shocking Grasp.
