First place very likely would be our discord, where most of the modders are:
https://discord.gg/ecoThey also have their own official community server which is pinned in our mod channels. The ModKit page on our GitHub might also be helpful, but documentation on things is still in a very early state, given Mod support is still in heavy development.
The restriction of this command is not based on 'cheating', but rather the commands original intention for QA and the fact that it might do things that are unexpected by a user. All commands that were made for this purpose and have never been built for admin use in a safe way are marked this way, no matter if these are especially 'cheaty', especially 'dangerous' or can be used to destroy the server / other players fun; it's solely based on what the command was originally made for. There is only very few commands that became dev commands in a different way than this.
The usefulness of the command for general administration would just be a factor in determining if we ever make that command available as a dedicated admin command ourselves or if we don't. The use cases you mention rather seem like for testing purposes as a user than actual server administration and that is not really the purpose of our admin commands.
I also do use a modification on official server White Tiger that adds a command for our GMs that allows them to force other players to vomit. That is due to that server having constitutional laws that require a specific amount of food SP to be able to craft recipes of specific professions, a higher amount the higher-end the profession is. Given that is a very workaround way for improving on the situation that food quality does not play a role in Eco in the end game in vanilla, this leads to some brand new players getting stuck with their food bonus, not reaching the required values as they didn't understand that they have to eat high quality food. In such cases a GM can a single time per player reset their stomach contents. But as I said, even we use a mod for that.
