First, I'm not sure I either understand or am even aware of these alleged "forms of permission for announcement {that} are not documented". So perhaps Mr. Slater could elaborate upon that, for my benefit, and perhaps also for that of others who may also be similarly in the dark about what he's talking about here.
Route objects are not always required. While route objects are generally preferred and should be used, letters of authorization are still in use today. You certainly wouldn't see them in a public database (though you might see objects which claim to be tied to them). Even if you do, they may well be stale and no longer accurate.
I doubt that all (perhaps any?) anti-DDoS arrangements (which often involve apparent hijacks of blocks of address space) are documented with route objects.... ... although perhaps more so in Europe where I believe that some providers build filtering systems from route objects ? -- richard Richard Clayton Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.
