What else to say, good luck.

You didn't get the anecdote, that's probably because you haven't worked with PHP (long enough).

I will give hint: inconsistency.

Either working with PHP for 21 years is not long enough or simply too long. I honestly think these small inconsistencies are irrelevant in the big picture of building something complex. Like you said, programmers should deal with them. It just doesn't sound like a big deal.
