This is exactly what SPV libraries like bitcoinj do: they know how to build
a block locator, request the blocks forward from the common branch point,
and handle re-orgs onto whatever the current best chain are by downloading
data from a full node.
If your official position is people should all use bitcoinj to do things
like build extra indexes, then great. Send them our way. It already knows
how to calculate a UTXO set indexed by address.
