✅ Looks great and this is a really nice improvement that was overlooked!

🧪 Manual testing works well and test coverage looks good.

❓ Thoughts on this being a feature rather than a bug? Our command's help clearly documented that there were no arguments and the logic prevented extra arguments. To me, this looks like an enhancement and semver:minor 😄

[mwbrooks]

praise: Ah, much more elegant!

[zimeg]

@mwbrooks Thanks so much - I was confused to find this didn't match the create command which is what motivated "fix" and perhaps the comments adjacent sidetracked me...

But I notice now that documentation reflected what was found in releases so I updated this to be a "feat" and will merge it as such! 🚢 💨
