09/27 at Leeds wasn't closed just to piss off GA operators, it was mainly to give Jet2 space for parking at the 27 end.
I recently bought a aircraft and it's based at Leeds. Shares in it were so popular I'm probably going to buy another one, also to be based there. The only current constraints for GA at Leeds are the amount of hangar space Multiflight have. Oh, and it's not cheap, but you get what you pay for!
I don't think you have anything to worry about as regards GA there at all. Whilst I can see some airfields making it difficult for GA operators and squeezing them out, having an organisation like Multiflight with a large flying school and a large number of home-based operators does quite a lot to cement GA's position.
Not that I'm saying it will never happen of course, just that in my opinion Leeds is one of the regionals it's least likely to happen at.
