Should we go with the gcc-reparent.git repo now?

Where exactly should it be installed under https://gcc.gnu.org/git/
Replacing the existing gcc.git will be confusing, but then how would we
name the repo that will become the main git gcc repo in 2 weeks?

Where are the tools/scripts that should be installed on gcc.gnu.org to
keep it up to date during the next 2 week transition period?

Thanks,
