Hi,

Not to start a controversy here, but, for the use cases we have, this is more of a convention to keep order, and not necessarily, though some details, something that has to be. Although, now in 2025, I feel like, the deps and devDeps separation is still going stronger, and stronger than ever. I've sat through discussions, threads, etc, where all sides have made very valid claims.

• Clarification on using dependencies or devDependencies webpack/webpack#520 (comment)

And this had some back and forth in create-next-app as well:

• Add prompt for ESLint to CNA #42218 (joins the deps)
• fix(cna): separate dependencies/devDependencies #55730 (separates them again, current form)

And even in some React docs, they use this plugin as a devDep, and other just dep:

• https://react.dev/blog/2025/04/21/react-compiler-rc
• https://react.dev/learn/react-compiler#usage-with-babel
  Anyway, thanks for the submit.
