They are footballers, not Siamese cats. If part of the reason is about continuity and stability, it is a very small part, and the rest of the reason is down to a lack of ability. Delfouneso's loans have been augmented with little ventures into the Villa squad where he has done nothing. I think he has 12 goals in 69 appearances for all clubs since he started out, not great. Mind he is still only 21, but in any case he is terrible, and will end up playing in L1 or lower sooner rather than later, and you can quote me on that.
