@eiriktsarpalis in #82179 (comment) you wrote that "IncrementalValuesProvider also has a RegisterSourceOutput which can be triggered independently for each of its components without forcing recalculation of the others."

Do you have examples? I couldn't find an appropriate extension method.

@Tornhoof the more accurate statement would have been that IncrementalGeneratorInitializationContext has an overload that accepts IncrementalValuesProvider:
