One option would be to split git into two binaries: "git" and
"git-tool". Obviously the latter would be plumbing.

We could slowly move the documentation to git-tool and by doing so we
could see that if a porcelain man page has too many links to git-tool
documentation, that's some area of opportunity.

Every time you access a git-tool command inside git, it still would
work, but you will get a warning: "you are using a plumbing command,
use git-tool instead". Scripts could enable GIT_TOOL_MODE=1 if they
are going to access many of these commands and don't want to

I would be a ton of work, but it's something I see value in doing.
