That's true about the heat shield, the exhaust guard never gets overly hot and I never burned myself on it.
Iv'e thought a lot about sliders for a long time without reaching a good conclusion.
I think the problem with most frame sliders is they don't really slide because they are either too pointy or too weak to endure/disperse energy so they just bent and pierce into the plastics instead, perhaps only useful during stationary ''drops'' instead of crashes.
.And If they are strong but pointy they result in all the energy being focused on the frame which, like Cahuna said, could be a nail in the coffin.
The strong but pointy ones have a positive if you look at certain brands, like SHOGUN or R&G for example use a sortoff '' soft rubber material''. The material is eaten away during the crash dispersing energy, they also use strong metal bases so you can expect them to not bend or focus energy as violently. (
) good example video.
Problem is... last I checked SHOGUN and good quality sliders cost 350eur, for that amount you might as well buy new plastics... (also most on our bikers require drilling holes into the plastics) AND they are a one time deal, you crash with them at speed and you have to replace them.
OEM plastics are very strong, and at the end of the day are the perfect sliders... it's just a shame they are so **** expensive and without sliders no matter the speed of the crash they will get scratches and ruin our bikes look.
Iv'e heard of people buying chinese aftermarket fairings, they ride with them effectively using them as sliders and keeping the OEM safe and sound at home. It's a good idea except chinese fairings are very brittle, so allthough cheap they wouldn't do a good job as sliders.

^This design is interesting, looks more ''sliding'' friendly, but if its not strong, I can see it bending inwards into the fairings and causing some damage :/
So iv'e crashed on both sides of my bike without sliders, at fairly decent speeds. and both times damage was focused on the plastics, the bar-end weights, exhaust guard, passenger footpegs and gear shifter. passenger footpegs still look fine, gearshift had to be fixed, but replacement wise is say it all falls to the plastics, exhaust guards and bar end weights. All pretty much equal to the price of high quality sliders. (maybe a tad bit more expensive). So I dont think its really worth having sliders on this particular bike.
