Totally agreeing with this but the issue is maintenance. Sure, I can find a package and copy and paste a few files and make it my own — or do it from scratch even! But then, that's not really my core domain, so I'll most likely never touch that piece again anytime soon. A quality package tends to have that covered (with a small risk, too if it's an untrusted source).
