Sure, that makes more sense I think.
As a motivating use case, Bitcoin Wallet for Android currently has a
hard-coded block explorer (biteasy.com) which it uses to find UTXOs for a
given key. This is used for its "Sweep paper wallet" feature. It must work
this way because P2P nodes don't calculate such indexes.
If there was a way to do block index autodiscovery, that'd help us remove
this hard-coded block explorer and increase decentralisation. But because
it's a GUI app we don't want users to look at a spinner for more than a few
seconds, so a slow discovery process would make it unworkable. With
API-based categories of service bits we could implement such a scheme.
