Well, first of all RFC3021 made back in December of 2000 says you can do a /31 on PTP links just fine ;)
Secondly, if you're in the situation where you have a single flow that needs more than 1Gbps, your options are very limited. I agree it's not the best solution if for whatever reason that you have no switches at the site, and I'd also say than even with hardware offloading LAG/LACP really sucks balls over wireless due to the changing throughput of the links... but yeah. It does work, but again - there really needs to be a layer2 or layer3 based protocol to handle this kind of thing.
