Sure, but you could always just use a different name. e.g. I just have git p aliased to git push --force-with-lease, and i almost never use git push anymore. (im not sure what your usecase for the reset command is, but i have a git wip command thats basically an alias for git add . && git commit -m wip --no-verify which i use a lot)

Also, cant you define your cd subcommand using gitconfig aliases?

Nope, that doesn't work either. This is the only way AFAIK to override a built in git command. And I don't want to retrain myself to use an alias -- it defeats the purpose, the moment you slip will be the moment when you shouldn't.
