- Don't attempt to insert fixes if there are restrictions present, they'd inform the failures. Inserting fixes too early doesn't help the solver because restriction matching logic would record the same fixes. - Adjust impact of the fixes. Optional conversions shouldn't impact the score in any way because they are not the source of the issue. - Look through one level of optional when failure is related to optional injection. The diagnostic is going to be about underlying type, so there is no reason to print optional on right-hand side.
