Does Geckolib API create an noncircumventable dependency for the user?

I want to create a custom animation for a custom model and have found that the only way to do this is with GeckoLib. I would like to do it, but from what I heard the users would have to install GeckoLib for their Minecraft to run the mod. I don't like the idea of forcing users to install another mod just to run my mod. Is there no way that I can add the animations through files or code so that this dependency isn't needed? If not, I can just bite the bullet.

Thanks in advance for reading.
