You call into dynamic libraries so that you do not need to recompile and distribute new binaries to all your users whenever there is a security issue or other critical fix in any of the dependencies.

But if I get to Bring My Own Dependencies, then I know the exact versions of all my dependencies. That makes testing and development faster because I don’t have to expend effort testing across many different possible platforms. And if development is just generally easier, then maybe it’s easier to react expediently to security notices and release updates as necessary.. .
