Another option is to generate a key and put it on an offline storage, and have a second key only in the SE. This means you'll need to upload two public keys to places to have a backup instead of one, but I think would otherwise achieve the same thing.
The nice thing with this is you can keep your backup public key easily accessible. I try to keep a primary and backup Yubikey on everything important, but you have to physically get the backup Yubikey in order to add it to a site.
Evaluating the content on its merit I'd question whether the author has seen a bicycle before. Yes, in the final iteration with Opus it added a chain, but it's missing a triangle which clearly shows a lack of understanding of mechanical relationships.
Ignoring the wording, em-dashes, etc. I'd assume an LLM not only wrote the article but also judged the pictures. That or the author has a much more relaxed opinion on what a pelican on a bicycle should actually look like. I don't think I would call Sonnet's arms and handlebars improved, nor would I call Haiku's legs and feet "proper." And if you overlay GPT-5 Medium's two photos the shapes proportions are nearly identical.
