These options class, unlike most/all of the others, are final.  This makes it awkward for me to provide a consistent experience in Morphia.  With the others, I can extend them and add things like WriteConcern and ReadPreference options to provide a single place for users to define various options.  With these being final, i have to jump through certain hoops and it results in an inconsistent API and implementations.  'final' should be removed from these types. I can work around it but it makes me sad.
