"I see pages doing it is that they're up to no good" well that is your 
opinion, sure, we have all seen bad use of that,  but removing 
functionality that has no replacement, can be used for useful thinks 
(well for bad as well) can hardly be reasonable, because you may not 
like some of its usage. I've seen several as well, but I also know about 
some useful usage, that either cannot be do other way or would require 
overhead.
