I put myself in very uncomfortable position. When I need to prove my words by blaming someone who did very good job for the community in general. At least have these good intentions. And the same time I don't want shame somebody in public.

I did some research and think this link is enough https://github.com/pypa/pipenv/issues/1137.

Wow... some users are subtly pressuring the maintainers into work here. The maintainer simply states "works as intended".

The users in that topic then continue the discussion in all of its aspects, expecting the maintainer to engage with them. I can imagine it feels to the maintainers as an energy-sucking discussion.

IMHO, you're not shaming the maintainers, you're shaming the community here.
