[Openstack] Cells use cases

Hello all,
I've really interested in  cells but unfortunately i can't find any useful
use cases of them.
For instance I have 4 DCs and I need single entry point for them. In this
case cells are  a bit complicated  solution. It's better to use multiple
regions in keystone instead

The only one good reason for cells, which I've found, is
to organize so-called failure domains, i.e. scheduling on another DCs in
case of failures.

Does anyone have different use cases or vision on cells usage?
Thanks in advance.

Kind regards
