Not sure what difference that makes? An enabled exchange doesn't necessarily mean anything for individual cabinets as the costs for a cabinet can be excruciatingly high as has already been covered in this thread.
You said 'We don't know how much it would cost to get BT into your area' they are in the area, just not to those cabinets.
If Openreach didn't promote messages such as 'exploring solutions' and were just honest and said no way - it's too expensive then we'd have closure on the matter. But to constantly dangle the carrot of 'it might happen' or as in their latest email to me 'There are projects to be initiated in 2017, however, we do not have a particular timescale at this moment' is taking the pee.
You are honest in your assesment of the situation - maybe if Clive Selley turns round and tells me to sod off elsewhere I'll shut up. Whilst the carrot is there I'm the donkey trying to reach it.

Exchange is Fibre enabled, Cab not economically viable to upgrade - though 'Now Exploring Solutions aka we want someone else to pay for it.'
