Developing 'module' package type overrides 'Always Visible'

I’m trying to develop some packages using the ‘module’ package type, but this type causes the package directory to be hidden in the project view, even if Visibility In Editor is set to Always Visible. So a person can’t navigate to the Runtime folder or Tests etc while developing it.

I couldn’t find any documentation on what the ‘module’ type means, so maybe its meant for internal Unity stuff?

My mistake, I guess I just didn’t see it in the manual, and unity even replied me a year ago telling me this
