A mainstream hardware company releasing a specific product SKU to support third party firmware really sounds crazy from the perspective of the current market where a substantial portion of the value in selling hardware is supposed to come from subscriptions and surveillance.
Despite this, I could expect 3-5 people to hunt me down at PyCon when I was running the wireless to tell me that I had misconfigured the wifi because it was set to low power. More reports of that than reports of wifi not working, IIRC. ;-)
(I was running the wireless because the people we paid do to the wifi would just set up one or two APs and crank the power)
Only if your clients are competent at roaming.
