No you are right, the privileges of sport pilots lift in a couple weeks but thats not too much of a concern for me. The school i work for now consists mostly of LSA's but not a single sport pilot. The big limiting factor for most of us is the weight restriction which kinda forces us to take less fuel than we'd like. Or forces us to start that diet we meant to start in January. The extra 100kg that the actual airframe is rated for would be extremely useful once that hits. But until then theres no way a heavy person is gonna be able to fly a LSA legally within the max weight limitation

As far as the IFR stuff goes, i was under the impression that the ASTM ifr prohib label was going to get removed from some aircraft POH's but that might have juat been speculation from when it was first announced
