So officially any project in the jenkinsci org should be going through a HOSTING jira request. When its not a plugin its a little less but all repos should have a ticket. Especially since the approval bot stuff creates a jira component and a github team.
As for the actual request, I'm +1 to having something in the org that is being maintained. Lots of people have made stuff over the years, often curl scripts, often hidden deep inside companies, so i'd love to see more cli tools for people to use and build upon.
