In addition to other advice here: If you want to save on keystrokes, set yourself up a shell alias that’s short but unlikely to be a valid command anywhere else.
I have one that’s kind of the inverse of yours, called mntStorage (no prizes for guessing its purpose). It wasn’t intentional, but mixing case like that is pretty rare in important commands too.
GNOME and its applications have been headed in that direction for a while now, but I’m not sure Canonical are behind those changes. If they were, I’m sure they would have done something about GNOME apps looking alien on Xubuntu, for example.

As that link suggests, the Mint team are looking to produce apps that run on any desktop environment, forking GNOME apps that don’t comply with that. Hopefully that keeps the momentum going for that sort of thing.
