That's literally clarified in the Reddit comments. If a new option is added in the future, it will just say `git --am` is ambiguous. The git man page explicitly says that if you're writing a script of git commands, you should use the full option name, so you won't encounter this ambiguous issue. So no, it doesn't constraint the evolution of the API.
