>"to use a tool the way it was intended you had to adjust to use the tool as it was intended to be used"

I sure wouldn't call that a _bad_ UX. As with any tool you have to adjust to the tool or make your own unless by some miracle someone shares your particular idiosyncrasies.

>"modifying tool makes it different from your co-workers tool"

Yes, but that is a big plus instead of a minus. If your co-workers asks how to do something you can just give them the content of the alias. I also alias `git` as `g` in my terminal. Is that going to cause problems for my co-workers? No.

Unless you are training a complete-fresh-out-of-school-junior the "new guy" should already know how git works and in either case that sounds like homework for them more than anything else.
