Ya this more matches my experiences as well!
I have one open source utility that has gotten a tiny bit of niche traction. Enough to get a small handful of issues, and one PR. But the issues came mostly at once when I posted about it, and have died off now. When I said I wasn't sure if I wanted to implement a feature the poster politely asked I consider it, but never pressed me on it again.
Maintaining a popular project is DEFINITELY a whole different beast. But I don't want to scare people away from open sourcing something they made, cause they were worried about about the burden of maintainer-ship. In my experience it's been a minuscule amount of work, and each interaction has showed me that others benefit from the tools I've made, which was my full point in open sourcing to begin with!
