Hi Hubert,
I do not have a specific timeline defined as of yet.  My hope is to get all
of the other projects under the llvm org migrated to using a 'main' branch
by default prior to the end of January 2021.  I do not control all of the
other repositories though, so I will be working with their owners to
accomplish this according to a schedule which will cause the least
disruption to the individual projects.

Thanks,
Mike
