> It feels like every modern realworld battleworn programming stack (ecma, c++2x, .net, jvm w/e) is filled with nuances and quirks which, as it turns out, an engineer _must_ know about to be able to bump revenues a little bit and to call themselves a professional.

I think you are overestimating how important those nuances are. The differences between Python and Ruby are not significant. The differences between Java, C#, or Golang are not significant. If you are a trained software engineer and have coded with one managed memory language, one garbage collected language, one typed language, one untyped language, one functional language and one object oriented language you have seen 99% of what there is to see. Most computer science grads should graduate having programmed C, Java, and Python
