I'm considering releasing the source code of an App as Copyleft, but would like some individual components (just not the core project) to be used under a more permissive MIT license.
How would this work? Can I have a top-level LICENSE file that's Copyleft, and then contain LICENSE files in sub-directories or at the top of files, and specifically state those directories (or particular files) are MIT licensed?
Would this cause issues for large organizations that scan for Copyleft software and prevent their developers from using it? I'd expect that, since it would be copied instead of downloaded through some package manager, it wouldn't be an issue for those developers, right?
Thanks in advance!
