There is no "wrong" design in git.  There are ones that do not cover 360
degrees of the field, because nobody designed out let alone coded to cover
such use cases.

Changes to parts of submodules are fundamentally different from changes to
parts of your main project.  A change to what commit the superproject
wants for a submodule is at the same level as a change to what content the
superprojects wants for a blob.

It is not unreasonable to want to have both modes of operation, one that
shows the uncommitted details in the submodule even when you are viewing
from the superproject (which does not exist), and one that does not (which
does exist, because somebody felt need for it and coded so).

In order to see the status of your working tree, you may want to take into
account what untracked files are in there, but some people do not want to,
so there is an option to pick which behaviour you want.  We would need a
similar switch.

Yup, that's the spirit.
