Why on earth would a VFR flight request a PS?
Well, quite...
But probably because (a) they will be entitled to - the CAA is now encouraging it, (b) for the same reason as "why climb a mountain?" and (c) they might be flying in cr@p weather conditions. However, it will cease to seem like a Good Idea when they are required to climb another 5000 ft and probably go into IMC.
Agree entirely with the comment about non-radar aerodromes - it really has not been properly thought through.
