I don't think you need to worry about the short course ending. It is a replacement for DESO recruitment, only takes a couple more months to get someone online but they only pay half what they need to for a DESO for the first two years which then drops down to only paying about a third of a DESO package for a couple of years and then back to paying about half for the next 6 or so years when a JFO/FO. Intake for the short course will probably fluctuate more with the requirements of the airline for new pilots but I doubt it will end soon.
