The only real reason to segment these networks is to prevent broadcast storms, and the wireless controllers tend to have built in broadcast suppression rendering this harmless. I changed our main SSID from several /22s to a single /16 a while ago to negate the need to keep adding more subnets as the usage continues to grow. We've seen no problems with this whatsoever so far. Keep it simple!
