Biggus, the WSO school and the Dominies were going anyway and SDSR only hastened their demise. The original plan was the WSO / WSOp trg was moving to MFTS along with RN Observer trg. If the RAF continues to have a WSO / WSOp requirement then it will (as it only ever was going to be) be done under MFTS.
Not saying that I like or endorse the above but as you started drifting towards 'facts' I thought you may appreciate some.
