The upcoming lazy import system may help with startup time…but if the underlying issue wasn’t “Python startup is slow” but rather “a specific program imports modules that take a long time to low”, it’ll only shift the time consumption to runtime.

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.
