as long as it's deemed neccesary, I guess...
Nope...Seedcorn has a natural shelf life, and it's not far in the future. Since Seedcorn is "seeded" with operational combat ready MPA aircrew (which we don't have anymore) it's shelf life kicks in at the tourex of the current shift.
No doubt there will be room for the odd extension or two if the talking heads are still vacillating about the future MPA capability, but expect it to fold pretty quick not least because the individuals concerned will be thinking "nice gig, bwtf is my life/career going?".
Of course it may mutate into something else, but then it won't be Seedcorn any more will it?
