I'm not lamenting it.  What sent me off on that tangent was MUSL
handling of %s

  https://www.openwall.com/lists/musl/2018/01/18/4

that causes some tests to fail b/c it behaves differently then other
implementations.  As I said, I'm not familiar with the lore of this
API, so I was just seeking clarifications and venturing some
(un)educated guesses.

Thanks for your input!
