Nah. I made plenty of software and then abandoned them because I lost interest in them. My GitHub is already a fairly large collection of my own abandoned software, and there are 10x more on my PC that I never bothered to upload to GitHub.
Easy abandonment is always there.
Not at all the same thing. Your half-baked works can't appear to be anything else than what they actually are. You are in no danger of wasting anyone's time.
For one thing, you probably never tried to mislead anyone. Did you put 8 minutes of effort into something and then come here and try to say "Hey world, here is a thing you should all care about and invest in. I mean, I didn't, but you should."?
But even if you did try, you physically cannot (5 years ago) generate the equivalent of 10 years of work by a 10 person team complete with docs and tests that all looks plausible and maybe even runs.
