Sliders are actually just unnecessary bloating, because users just don’t use them. Sliders make a site just heavier and are more or less just old hype than something needed…
But sure, it should or would be an option if a webmaster wants to use such thing for some reason.
In the bigger context - everything that makes harder to reach real content - meaning one mile long scrolling 
- is always bad idea. Same thing than why e-commerce tries to find shorter way from product to checkout.
Yes, I know - off topic. Sorry.
