Mostly compatibility. GNU's libc and Alpine's libc implementation should match the same ABI but might not be 100% the same

Yeah, because of that, it's really hard to get Alpine-based Docker images to work in some situations, for instance:

this: https://github.com/grpc/grpc/issues/18150#issuecomment-47999...

And this: https://github.com/pypa/manylinux/issues/37

I use Python. Anytime you need to compile the source to build a pip package and that the upstream package developer decided that they don't support Alpine's libc implementation (aka musl) then you will have a big problem, unless you can control your dependencies and include as few pip packages that requires compilation or find binary builds.
