A few reasons.
Power has never really been an issue with the X and Y axis, 2 small steppers work fine even for aluminum, I used 42oz/in from an old printer for 6 months and never skipped a step and had them undervolted as well.
Most people use this for multiple things and use the other ports.
Running your steppers at max power causes them to be extremly hot, applications that momentarily use the steppes it is fine but under several hours of continued use max amps is not suggested.
