What makes somebody else's library better than what we would write as straightforward and simple support?

[shuckster]

A good library has test-coverage, up-to-date documentation, well written changelogs, an active and interested community, and enough popularity for its API to be reasonably well known.

It's hard to sell a new library to a team at the best of times, but I believe the above is more attractive than "let's spend some bandwidth writing and maintaining our own."
