Unfortunately, the extent to which these sorts of guidelines will ever be followed is at most the extent to which programmers feel like putting in extra effort over and above that required to meet business requirements, and will usually require programmers to push back against business requirements in order to achieve any headway.

Those little social buttons that track every user and nobody ever clicks? You're going to have to spend as much time making the case to your boss why they're a bad idea as you would simply implementing them. Ditto ad spam, interstitials, sticky banners, and the like. And if the UX is bad but conversions increase, good luck.

These sorts of guidelines are great for small sites you control yourself. The chances of being able to follow them, even if you give a shit, on a corporate site where conversions put food on the table, is essentially nil.
