@decyjphr Hi Yadhav.. Looks like this is still in draft. Is it ready to get submitted to merge?

@thebollywoodguy I am still working on it. Right now, the issue is if settings.yml or repos/repo.yml is modified, we load all the suborg configs and so we can determine if a repo has multiple suborg configs, but if a single ../suborgs/.yml is modified, we only load that suborg config (for efficiency) and so we cannot determine if the repos for it is also present in other suborg-configs.
So there is some more work remaining to handle that scenario.
