Tests that explicitly create RandomState objects would not be difficult to
migrate. The goal of "StableState" is that it could be used directly in
cases where RandomState is current used in tests, so I would guess that
"RandomState" could be almost mechanistically replaced by "StableState".
The challenging case are calls to np.random.seed(). If no replacement API
is planned, then these would need to be manually converted to use
StableState instead. This is probably not too onerous (and is a good
cleanup to do anyways) but it would be a bit of work.
