I am inclined to agree here. What I don't know about is the cases noted in the bug, such as GraphQL or other serialization cases where "null" and "absent" are not quite the same thing. That is probably sufficiently edge-case to not deal with directly, especially when the more verbose alternative still exists, but that's the only reason I'd even consider making uninitialized something other than "your constructor is bad and you should feel bad." --Larry Garfield
