Personally I think 750kg and only 2 seats is more than enough, it would allow LSA factory builders to make their aircraft a bit stronger and allow existing LSA's to have a bit more leeway as far as passengers and baggage etc, some are already very close to the 600kg when loaded up with crew, bags and fuel.
The new generation of LSA's would be stronger and have more load capacity and in the end be safer, so that's a good thing, so as I have said I think 750kg is more than enough. I think we could have some very nice RV's then included on the RAAus register....I will have one of those please...
