I'm a little worried about having warnings that are disabled by default and potentially hard to discover.
From offline discussion, some possible mitigations:

• leverage an existing flag from SDK to activate those warnings
• give some unobtrusive hint in IDE that something is going on (we added a default assignment for you) and some warnings could be turned on
• confirm that some customers would really benefit from those warnings (runtime?) otherwise consider removing?
