Is there any concern why folders named 'lib' are git ignored?

I'm trying to create a RN library with create-react-native-library, but should i be worry about why the lib folder have to be git ignored? Just curious, and that's just a naming convention of mine that i give a name for a folder. I can use another name though.

lib/

Nevermind. I saw the bob build script.
