Review Comment:
yea I was initially thinking a separate one will be more clear .

Review Comment:
Also seems like we should implement this for all the catalogs, or at least
error there if this path is chosen.

Review Comment:
Should probably be called 'forReset()' or something more descriptive. This
is a bit ugly but couldn't think of a good way to avoid it. I suppose just
having a metadata with a location != null , regardless of whether base is null
or not , is not enough to signal its a reset? @aokolnychyi @RussellSpitzer
@rdblue for thoughts?
