Should I use this library?

I'm considering using <library> for <purpose>. Stack: <stack>.

Assess it:
- Is it actively maintained? When was the last release, and how
  responsive is the issue tracker?
- How big is it, and what does it pull in with it?
- What's the licence, and does it constrain what I can do?
- What's the realistic migration cost if I need to remove it later?
- Is there something in the standard library or the platform that
  covers my case?

Then: what would I have to build myself, and how long would that take
including the edge cases?

If you're not confident about the current state of this library, say
so rather than guessing.
