I think I encounter an example with conduit-find package.
I found the package useful and fixed issues, send a PR based on somebody’s else PR a few years old. Last commit in repo was 7 years old. No response until I raised a question about maintenance transfer. Maintainer closed PR without any raising any review issue, but released something as he promised on time. Today I tried to switch from internal cabal package to hackage, but discovered that released package has a few failing tests.
