Hi Hank, I think you're right, it could result in sub-optimal routing and in particular, in your AS not being used for these subprefixes (the traffic will go instead to a competing provider who sent the subprefix), hence, as you said, sub-optimal routing.

Incorrect - you hold the full table in RIB, which is what you offer to your downstream customers.

It's the FIB which wouldn't have the route, but would still be able to forward the traffic to a router that knows better.

Downstream customers are none the wiser.
