Deferred standing is standing extended in advance against an expected future payoff. It is one of three layers worth distinguishing: pure standing (you count because you are here), deferred standing (you count because we expect you eventually to justify the support), and earned standing (you count because you are currently producing recognized value). Much of what looks like unconditional standing is really the middle layer wearing the clothes of the first — a child carried for who they will become, a trainee funded because they will pay it back, a person tolerated as long as they are trying.
The layer matters because its condition is invisible until it is triggered. The only reliable test is whether standing survives the disappearance of expected return: does the participant still count when the future they were being carried toward is ruled out? If the answer changes, the standing was conditional all along — it had simply not yet met the moment that revealed it. This is why the person for whom both present and future usefulness have failed is the hardest case for any ecology, and why the children exception proves less than it first appears. Genuinely unconditional standing is standing with no deferred clause at all: it does not wait on a return, and so it cannot be revoked when the return fails to arrive. See the fear of being nobody.
