Ted Dunning commented on MAHOUT-510:
------------------------------------
The deletion of ModelSerializer in its entirety is a real problem because we
lose the writeBinary method.
Losing the JSON stuff is fine, but writeBinary is the only way to serialize SGD
models properly.
> Standardize serialization mechanisms

> At the moment this is tracking a broader concern: to standardize as much as
