I agree 1000%.  It may be convenient for existing scalar users to have
a way they can stick with the CLI that they are used to, but before we
add this functionality to git proper, let's please make sure git users
get a CLI which makes sense and not dictated by history.

We already have enough people who complain that the git interface
design is hard to understand but which can't be changed because we
bias our UI design in favor of existing users as opposed new users.
Given that I'm an existing user, I'm actually not complaining, but I
do recognize the validity of the complaints that for example, git
reset does three different, mostly unrelated things.

Given that the existing scalar users are used to "scalar <foo>" and
not "git scalar <foo">, I'd gently suggest that it's better that there
be an existing compatibility program which translates "scalar <foo>"
to whatever git command(s) makes sense, as opposed to optimizing for
the simplicity of said program so that all forms of "scalar <foo>"
should get translated to "git scalar <foo>".

So for example, if we are inside a mono repro, it would seem to me
that "git commit" should automatically do the right thing, as opposed
to imposing cognitive load on the user to know when they are supposed
to type "git commit ..." versus "git scalar commit ..." versus "scalar
commit".

Please, let's design the UI for scalar integration into git with deep
sympathy for the users, and *not* the convenience of the compatibility
script for the existing scalar CLI users.
