This is a mis-characterisation of the situation. In APNIC, we have
implemented abstract routing management: you tell us the routes you
want to declare and have to elect to do ONLY route: object or ONLY ROA
-we make the ROA & route: objects aligned, to represent what you asked
for in the abstracted route. It's only if you specifically ask us to
make discrete, unaligned states in both worlds we do that. By default,
they mirror each other (modulo the limits of maxlen over the prefix at
hand: we don't make the "forest" of routes which would be needed
beyond a small distance maxlen - prefixlen)

Separately we kept the old whois object update path. you can elect to
make a route: object directly in the RPSL maintenance engine. If you
come into routes management, we flag the mis-alignment such as it is,
and you can make the ROA.
