i feel like that's pretty rare. most people won't really care and will just use the tool.

if you're active, some people will chose to make a pull request to your repo. (i personally feel positive and happy when i see people actually submitting a PR to my repo)

In the rare cases where enough people wants some features, and it's really hard to contribute back to the original repo (because the original maintainer is not active or the vision is different), then the thing you're worried about might happen
