I don’t have any hard statistics to back this up, but I’m willing to fake bet that at least 90% of Mist’s customer deployments use local breakout (LBO) or local bridging as the method of offloading Wi-Fi client traffic onto the wired network. If this is your first time seeing the term LBO, it’s essentially bridging traffic directly onto the switch port that the AP is connected to. It requires a L2 network where your client VLANs are available on the switch(es) that your AP(s) are connected to.
