What's exactly the guideline for choosing between the "Library" and "Extension modules" section when updating Misc/NEWS? Is it just the fact that the modified files live under Lib/ or Modules/?
I've frequently made a mistake when updating Misc/NEWS, and when looking at it, I'm not the only one.
Is there really a good reason for having distinct sections?
If the intended audience for this file are end users, ISTM that the only things that matters is that it's a library change, the fact that the modification impacted Python/C code isn't really relevant.
Also, for example if you're rewriting a library from Python to C (or vice versa), should it appear under both sections?
FWIW, the What's new documents don't have such a distinction.
