it is only when you get down to someone who has [a piece of] that
allocation they wish to announce into bgp that they acually cause a ROA
to be issued which may be validated using the cert chain.

this is easily done with the rpki, up/down, publication, ...

exactly. but only if the parent runs the up/down ('provisioning')
protocol, does the child have that choice.
