I am a bit concerned that in message 5, SAS says that someone that was thought to be incapable of reaching the required standard was sent solo.
My understanding of the competence required to go solo suggests having enough skill in all of the critical stages of the aircraft handling/procedures/co-ordination to be expected to bring the aircraft (and the student!) back in one piece. All that you do after that is adding the judgement to do it unsupervised.
Wouldn't getting to this point suggest that someone is capable of going on to get a licence?
As an aside, a few years ago I (a low hours microlight pilot at the time) was having dinner with a recently retired airline pilot (gazillions of hours) some where in France when he came out with the self evident fact that you actually become a pilot when you complete your first successful solo circuit.
