If by 'they' you mean the planners then they should because it will keep jobs and a vibrant organisation
If you mean the owners then it depends on whether thy have any real interest in aviation or just want to be developers
I think this is too important to be left to owners and should be encompassed in law, but as airfields have been declassified into brownfield sites and central government has no interest in GA.....
I was hoping the planners might have some b@@@@ and insist on it
