As first explained in https://discuss.flarum.org/d/32807-ideas-of-maintenance-commands-that-could-be-useful-in-a-chore-extension, this extension came from the need, in multiple extensions I maintain (all of them in fact 😅), for a command that would re-parse all the past comment posts using the new formatter's configuration. But more of these maintenance commands could be added later, this is why it has a generic name.
So if you are like me and you have extensions that modify the parser, you can suggest to use this extension in your README and with a suggest block in
"club-1/flarum-ext-chore-commands": "Allows to reparse all the comment posts with the new formatter's configuration"
You are also welcome to suggest new commands to add that would fit this extension as "useful general maintenance commands".
