If you open the assessment document, you see the responsible division is HOME.D4 - The Home D4 unit is part of the Directorate-General for Migration and Home Affairs (DG HOME) within the European Commission (D4 focuses on Counter-Terrorism). They have a head of unit [1].

To be clear, the call for feedback happens _before_ a legislative draft is put forward as a proposal. The feedback will be analysed by D4, there will be things like impact assessment and finally the College of Commissioners will create a proposal for the Council and EP to start the usual legislation procedures.

PS: I’m not saying they should be shamed, just answering your question who is responsible :)

They refuse to disclose the authors. [1]
