Whats so special about East Hampshire – PD Exemptions no better than throwing pins at a map?

The list of exempted local planning authority areas from the office to resi  pd right.

Bizarre, many parishes in East Hampshire, some individual buildings ion Sevenoaks, and with a few odds and sods other than the Central Activities zone and K &CD (but bizarrely no other outer London areas) no where else makes the cut.  Why6 should a single office remain in Wandsworth, Richmond or Kingstone for example.  Crying out for a JR as I cant see any ryme or reason for it.
