Doing more-specific multihoming makes ONLY sense when planning to filter them at some point in time. Unfortunately at exactly this point, this scheme fails. This cannot be fixed in time and with education, this is a very fundamental problem of this approach.
No, it's not. Keeping the aggregate up isn't hard to do, and all the other stuff is even easier.
"isn't hard to do". Yeah, I have seen vomitting horses, right in front of the pharmacy. With prescription in their mouth. What do you do against intradomain routing problems? Loops? DDoS congestion? With proper BGP multihoming you (as end site) can just withdraw your announcement via this problematic uplink. Doesn't help you with more-specific pseudomultihoming and people filtering the more-specific. Traffic to you still ends up in the problem area.
