I know the current functionality is intended behaviour but i very much don't agree with that. We're running into users violating the law (mandatory rentention) by removing older versions of surveys they no longer want to use. I need to prevent them from being able to do this.

I appreciate the permission-distinction between own/other surveys, but i need to be able to set more finegrained permissions for own surveys as well. Being able to create a survey should not imply by default that you can remove it as well. Same holds for (de)activating.

I need my users to only be able to define and edit a survey and after activation they should be able to view (not edit/delete!) survey participants and that's it. Absolutely nothing else! (de)Activation, invitations etc is done through RemoteAPI by a different user that's added to the survey as a participant.
