I'm not sure if this is still needed, but I might be missing something.
Shouldn't this always be enabled?

> The current implementation of the serializers can be a
> performance bottleneck in some scenarios. These performance problems were
> also reported on the mailing list recently [1].
> E.g. the PojoSerializer uses reflection for accessing the fields, which is
> slow [2].
> For the complete proposal see [3].
