Aren't they doing it kinda backwards? Shouldn't you start with the pieces and then let people assemble them how they want?

It's fine to offer off-the-shelf supported configurations but why start with everything and the kitchen sink and then try to backtrack?

Because nobody would use docker if installing it required a custom complex build process. This way docker can keep docker CE for its standard use case but also satisfy power users with specific requirements by allowing customization.

I use docker because I can go from

"Hey cool project, I want to try it!"

To already setup in under a minute depending if I'm at home or not.

Also the VMs start really fast, so it's good for getting exotic compiler toolchains on Windows running quickly. Everything has a dockerfile.
