Imperial measurements

When I read that the government is going to review the use of imperial measurements, I thought they meant to phase them out. It would appear, however, that the government wants to bring back pounds, ounces, yards, miles etc. The UK went decimal more than 50 years ago, although miles remain standard measurements for road and other long distances. This is being touted as a benefit from Brexit. If adopted, I think it is one of the more stupid results from that decision. Even if the UK is no longer politically integrated with Europe, having one system of units of measurements still makes sense. It is called the SI system. However if we're so bent on returning to the past, why not turn the clock back even further and bring back hanging, public flogging, child labour and slavery.
