We have introduced the mentioned assembly in release Q1 2014 (2014.1.226). If the analytics functionality it is not used in your project, you need to locate the EQATEC assembly and set its Publish Status to Exclude just like you did.
We improved this behavior in our latest release Q1 2014 SP1 (2014.1.402) so it will not require this additional step.
