Yes, there would be an extra round trip for an agent that is not aware of the XRI http subscheme conventions.  But an agent that *is* aware of the conventions could inspect the URI and safely skip the extra round trip, in a manner similar to the optimization suggested for thing-described-by.org:
That seems like a reasonable trade-off to me: naive agents incur a small penalty, but agents doing high volume have the option to safely optimize.
