Why isn't it possible to gain a delegation by proving number

Because your ISP can't be bothered.
Is such unbotherability legitimate?
these years, it is one of the things when considering a provider from
which one gets address space.
part of the problem is that this used not to be the case. "rdns is not
really useful" was the common thought. so many isps did not pay it much
attention. now, more and more services are using rdns mapping to defend
against crapola. so it has become useful, and quite needed in some
cases.
but it is notalways easy to justify to management the costs of cleaning
it up, often involving your provider, sometimes your provider's
provider, and on up the chain.
RIPE could at least reproach those LIRs that have an inet6num but no rDNS
delegation to it.
BTW, how should one search DB objects like 2.0.a.2.ip6.arpa? I can search it
in the DNS but not in https://apps.db.ripe.net/db-web-ui/query
