This hat been discussed multiple times, and won't happen at it's a breaking change.

false only removes real boolean attributes. test1 is a custom attribute.

we should make this clear in the docs, that for custom attribute will only get removed if its set to null

Feel free to make a suggestion in the docs repo.
