Thinking on my earlier suggestion more, I wondered if using the OPT_SUBCOMMAND() function might make things easier to organize and eliminate the need for things like .enabled or having to define structs for each of the sub-commands.

But I don't think that this is (easily) possible to do, since `--exclude-existing` is behind a command-line option, not a separate mode (e.g. "commit-graph verify", not "commit-graph --verify"). So I think you *could* make it work with some combination of OPT_SUBCOMMAND and callbacks to set the function pointer yourself when given the `--exclude-existing` option. But I think that's sufficiently gross as to not be worth it.

Thanks, Taylor
