TC( is using IRRd 4.2, which has an RPKI pseudo-source with
exactly that. ROAs are downloaded from NTT. You can see how they look
like at:

But this is not used to create route(6) objects in the TC source, only
to invalidate route(6) objects that users create at TC. Mirrored IRRs
like RADB are not subject to RPKI validation, only to scope filter
(private IP addresses, private ASNs).
