Fixing toxic communities is work. While it would be a public service for the author to do so, she is under no obligation and probably has a day job and a life that take priority.
I praise community-builders and community-shapers and code-sharers and code-reviewers to the heavens, but I'm not going to knock someone who just can't be bothered to do all of that.
(I did something like that with a half-done binutils patch once. It wasn't committed, and I didn't expect it to be. But I was happier having put it out there, so somebody looking for weirdo-TI-COFF-format support maybe had a place to start.)
In a similar vein, I recently learned about prefixing a pull request on Github/Gitlab with "[WIP]", or a "work in progress", to suggest that the proposed changes are for informational purposes or not yet complete.
WIP is really used, and we even have documentation about it https://docs.gitlab.com/ee/user/project/merge_requests/work_...
