OTOH, 98% of elisp code doesn't care *that* much about efficiency. And
the programmers who need to write that 2% will look into it and learn
about the function call ineficiency.

As an example of the former, see how popular the (repeatedly
mentioned) dash library is. It's full of ineficient code (most
functions and macros are implemented in the simplest way, not the
fastest). Yet, it's very widely used among the repositories.
