Schengen EES System

Hey guys, I am travelling to Paris on 8th of April and exiting Schengen zone on 14th of May from Athens.I have read EU will fully implement EES system and will no longer stamp the passports. What should I do to make sure I have an exit stamp from Athens? I am from a third world country and need visa for UK/US and other developed nations and not having an exit stamp can cause problems for me in future… Should I ask the paris officer to not stamp my passport? Or will Athens officers still have stamps with them in May?
