Tubeless and UST;the future?

Just wondering when it is possible to use a tubeless conversion kit,with conventional tyres why do UST tyres have to be so much heavier?
Just taking a fairly typical tyre like a Conti Explorer,the UST version is approx 130g heavier,than the standard.Times that by 2 and you've added 1/2 pound of rotational mass to your bike.
Now I know you have to take into account the rim tape on a tubeless kit which might be 50g per wheel,but bear in mind also that a non UST rim is lighter than a non UST rim to begin with.
Apart from less faff,to set up why would you use UST,given the extra weight and cost of UST tyres and rims to begin with,particularly for xc use?
Surely there is still a soloution to be had, which combines the convenience of UST with the lighter weight and versatility of a tubeless conversion?
I remember seeing that Slime were developing a new tubeless system,that had a partial inner,that did away with the need for spoke bed sealing in WMB a year or so back.
Did anyhting come of it?
Are there any other developments for tubeless bike tyres on the horizon?

I think the problem with none UST tyres is the thinner sidewall and potentially thinner bead. Your sidewall is going to die much faster without UST tyres and be deformed in ways it was never designed to be.
I do agree though, a middle ground would be nice, bizarrely tubeless is always cited as being lighter although your tyres are potentially 130g heavier and you have a thicker rim strip + sealant.
Standard inner tubes weigh about 200g :?0
