If more than one of this command appear, drop this one. Put a warning in the help message that this happened. If all of this command resolve with "drop with warnings", none of them will be available.

If more than one of this command appear, then

• if all the others resolve with "drop with warnings," fine, this one wins
• otherwise, fail the whole program with an error, on startup, even if they didn't want to use this command. This is the default because the others are opt-in, but you probably don't want to use it on anything dynamically added.

If more than one of this command appear, ask the user to choose between them. The uniqueChoice will distinguish them. If two of the same command with the same uniqueChoice conflict, or if one of the commands insists on failing everything in case of conflict, fallback to drop with warning.
