> Do we lose anything without monkey patch on placement?

As Chris said it won't affect the placement API, but removing the monkey patching in the nova-api will mean that cells get iterated sequentially rather than concurrently in the scatter_gather* routines like when listing servers and migrations. If you only have at most 2 cells (cell0 and cell1 at minimum) then maybe that's acceptable. For someone like CERN with 70+ cells it would not be.
