Can a backhaul B5c be used as an AP?

As the topic title says can a backhaul B5c be used as an AP or is there any technical differences preventing its suitability?

I asked the support about this, they told me there was a test firmware to do it but it have never been released.

So I suppose it could but they decided not to allow it (tech issue? commercial issue?)

I also asked support and they responded saying B5c is designed as PTP device only?
