After a few months of printing with my Prusa Mk3 (with plans to get a second one soon), I have been wondering about making my third printer a home-built one was a larger print bed than the Mk3. One thing I wondered about is perfectly expressed in the title question.
Are there practical reasons to not use a stepper motor with lead screw for the X and or Y axes?
I am certainly happy with the GT2 belts used in my current printer, but I wonder if the design might be simpler with lead-screws on all three axes.

In addition to cost, backlash, which can be experienced in the Z-axis where threaded rods and leadscrews are mostly commonly used, would/could become an issue. The elasticity of GT2 belts generally avoids this issue for the X and Y axes.
It would be worth reading Tom's answer to Advantages of GT2 over a rack, which while the question was related to Rack and Pinion mechanisms, would also apply to leadscrews, in particular:
To avoid backlash and get the same kind of "tight" engagement, both the gear and the rack need to be made with very high precision. The carriage also needs to be very well constrained, because any wobble of the rack relative to the gear introduces backlash (or binding). Moreover, you also need to keep the rack and pinion well lubricated lest they wear out prematurely.

Cost would be the primary reason. You can engineer a belt driven system that will be equally accurate, faster, and with longer travel for a lower cost.
Lead screws are comparatively expensive. The cost differential dramatically increases with length of travel and speed with equivalent accuracy.
Lead screws do have a significant advantage of being able to carry a much heavier load while maintaining rigidity which is important for something like a CNC mill but isn't as relevant for 3d printing.
this is on the assumption when you say "Are there practical reasons to NOT use a stepper motor with lead screw for the X and or Y axises?" you meant that you are still planning on using stepper motors but considering a lead screw vs belts.
