That's totally fine, because many CLI tools are organized like `mytool subcommand --params=a,b...`, and breaking out those subcommands into their own modules and lazy loading everything (which good CLI tools already know to do) means unused code never gets imported.

You can already lazy import in python, but the new system makes the syntax sweeter and avoids having to have in-function `import module` calls, which some linters complain about.
