I suspect it is true of many aspects of "programming" that aren't
apparent until you've been exposed to a fair bit of code (esp stuff
authored by OTHERS!)

In school ("university" for right-ponders), many of the issues that
were brought up as "worthy goals" in language design seemed somewhat
arbitrary (at that time).  Over time, I've been chagrined at how
many of those comments/lessons have gained new voice!
     "Ahhh.... *that's* what they meant!"

It is also significant to consider the nature of the "coder" in the
calculus.  How high do you want to raise the bar -- and to what gain?

But, isn't this effectively not-including certain "modules"?  Or,
will the parser then note that you've attempted to use something that
is not supported?

Correct -- unless you can impose a discipline on the library designers.

I prefer leaner languages because they give me more flexibility in how
I address certain aspects (problems?) brought about by the language's
model without dictating how things *must* be done.

E.g., it was easy to make reentrant "standard libraries" (without
changing the calling semantics) for C decades ago because there
was no significant runtime "integration" of those libraries with
the "execution environment".
