Your assessment of the situation encourages mindless ignoring of optimization. It always depends on the situation. Stuff that is done once in a moon... idc as long as it's reasonably fast. For stuff that's on the hot path you sometimes have to pull up your sleeves and optimize where possible.

At work I just had to implement a heap just because the heap provided by the standard libs wasn't fitting our problem.

Please don't discourage people creating this kind of content. It matters to far more people than you might have in mind.
