Add objection: lower the score of The solution should add value even with error propagation enabled

Feels like this is outside the "semantic nullability" problem.

The problem of indicating whether or not a position can error in the schema is a separate, larger problem IMO that could require larger changes like adding even more types to the type system:

String
Option<String>
Result<String, Error>
Result<Option<String>, Error> 

This is a much wider question though and I suggest we leave it out for now.

I personally thought it should be lower importance too, but @captbaritone convinced me otherwise at GraphQLConf, though I'll admit I don't remember his argument!

The score was lowered in #1686
