There’s a solution to this problem: https://github.com/sindresorhus/hide-files-on-github

Additionally, your OS probably already natively hides files that start with a dot, so this is just a UI problem.

Please don’t “solve” this issue by moving files to a sub-directory. If anything, only leave non-config files there, it’s the obvious simple solution that most projects follow anyway.
