You are very close to solving a real business problem. The problem is not "how can I have SSH aliases on my computer" but "how can we manage, company-wide, who can access which SSH servers."

My company currently uses YubiKeys to support hardware-based individual SSH keys. These SSH keys are distributed with Ansible. It works but is cumbersome and lacks a single pane of glass.

What we would like to have: a list of servers, a list of users, user roles (via sudoers), and a WebUI to manage all of it. And I don't know of any tool to do this. Of course, there are tools like Teleport or SSH CA instead of SSH keys, but they are for larger organizations and are overkill for my company.
