I'll comment from the perspective of a casual user and someone who enjoys collecting and viewing people's decks locally on my machine. I imagine there are others like me in the community.
As someone who enjoys other people's decks:
- I would want to be made aware of if a deck had the ability to do something hazardous
- I'd want to give explicit permission to allow decks I've loaded to be able to access those "danger" features
As someone who enjoys making decks:
- Downloading, sharing, remixing, and reusing contraptions is what makes the Decker ecosystem so great.
- I'm sure there are many users who use contraptions and modules without knowing how they work.
- As a creator I want to know I'm not accidently adding hazardous elements to my decks. Especially if I plan to share the deck with others.
I hope that's helpful feedback. Thanks for taking the time to consider some of these thorny problems.
