I built such a merchant system handing out BIP32 addresses.=20

The gap size problem does not arise there since such a system has to =
have an extra database keeping track of requests, so there is no added =
cost of storing the key coordinates used by them. A scan is not needed =
the keys can be accessed at random order.
