Well re-reading the OP I would suggest a high degree of speculation here.

On the other hand there might some pennies to be saved for BA, with the work done by experienced/dedicated staff distributed elsewhere to lower paid employees. I suppose it all depends on whether the intention is to release the staff involved or move them to other duties as part of the wider pool.

As stated above it will be interesting to see what training is provided, or whether this all falls over at the first sign of IRROPS when minimum wage check in staff are sat trying trying to rework complex routings. My guess would be that many things that have hitherto been possible will suddenly prove impossible.....
