I've done this myself to a point, but the point I'm making is that there's so much of this flying around and so much debate about so many often-unsubstantiated 'optimizations' that there's often not any real reason to believe they are optimizations.

And if they're not, people are going to waste a lot of time trying to learn new habits, then find out that they are no better off or perhaps worse, except now they're stuck with new, bad habits to unlearn.

My argument is less with optimization than with spending too much time and effort attempting it without actually gaining anything, or having a reasonable expectation of the same.

I think the point of this is not to optimize for the sake of optimization but to solve a problem. People have problems and they look for solutions. They try anything that can help once all else fails.
