For SharedPoolDataSource the way it is currently implemented, yes; 
but similar to the statement cache, that class does not use anywhere 
near the full features of GKOP. It does not allow you to provide a 
pre-configure GKOP or support cross-pool maintenance. The only thing 
it really needs is maxTotal enforcement and a map of GOPs.  I guess 
having GKOP means you could make SPDS more full-featured, but I 
wonder if its not overkill.

Probably best to keep it around if we can find a simple performant 
way to maintain it.
