I think it's a bit dafter than that. The NHS Long Term Plan allocated some money to the Additional Roles Reimbursement Scheme (ARRS), so specific money that could not be spent on GPs (or nurses). Which isn't (in my opinion) crazy in itself: GP surgeries can be improved by having physiotherapists, pharmacists, etc.). But it seems to have resulted in quite a few GPs who can't find employment and quite a few places for physician associates (with uncertain value since they need to be supervised by GPs). It all seems a bit of a mess.
