I would guess that the minimum height limit is simply a question of
excluding the farther ranges of human physical variation so that
equipment can be designed for a reasonable range of people.  Yes, it
is necessary to consider short people as well as tall people when
building well-designed equipment.  Length of reach is a significant
issue when designing control panels.  There is a limit to how small a
person can sit comfortably in a shuttle seat (especially at 3 G) and
how small a person can be restrained effectively by the standard
shoulder harness.  Persons with overly small hands will find some
multi-button-and-knob joystick-type controls difficult to handle.
There are all sorts of pieces of equipment for the shuttle that make
loose assumptions about the range of size of the users.
