Please instead establish any kind of directory that is expected where all that project and tooling related meta files are kept, I would like to suggest a top level folder called "config" - but I really do not care, how this is called, as long as that top level config file annoyance will disappear forever.
I believe it might be acceptable to expect exactly one optional top level config file that might be called "configrc" that would contain only the path of that actual config path if this is not in a default place.
Thank you very much for your attention!
