How would you run a project like this? People come and go. People do a one-time contribution and then you never hear from them again. People work on a project for years and then just go silent. Honestly, credit where credit is due, but how is a project like this supposed to manage this?

You can have CLA without assigning copyright to the project.

You don't need assignment to the project if you are not planning to change project's license.

You do need assignment to the project if you need to ever rugpull the community and close the code

You could pick a license and not plan to relicense later. Like Linux.

What do you mean by 'manage?' In your mind, what are you planning to do in the future that you need my full copyright as a change owner?
