I'd be surprised if it is much of a restriction in real world use cases. Accessing my NAS over 866Mbps WiFi[1] caps out around 60MB/s, the same devices over gigabit ethernet hit around 120MB/s (the NAS delivers around 650MB/s over a 10Gb link).
[1] tested with multiple client/router devices, in close to ideal circumstances (few feet line of sight between devices, no other devices active on the network)
