I don't, and I don't suggest people do. Opsec on who controls your servers is compromised in a million other ways if you're a legit business, and even if it's important to hide, there's other low-hanging fruit. That said, if I had any servers I controlled with other online identities, setting up keys for those identities would be sane, and if I valued privacy over convenience it's not that hard of a tradeoff. But I set up my new machines by typing in my github username to authorize all the pubkeys in there, and for the most part update my old machines the same way - curl -O https://github.com/gauntletwizard.keys https://github.com/gauntletwizard.keys ; vimdiff .ssh/authorized_keys gauntletwizard.keys
