It is not a fuss over dimensional analysis. Using g as the field constant in N/kg is very important to reducing confusion in understanding. When calculating the force, F=mg makes sense if g=9.8n/kg, but using acceleration doesn't make sense to students. They see it as being nonsensical because the object is not necessarily accelerating. The acceleration units are extremely confusing. I can remember being puzzled by F=mg and thinking that it made no sense because the object was standing still. The resemblence to NTN2 is obvious, and can cause great confusion.
1) Bad terminology will make problem (A) worse, but good terminology
will not solve problem (A), not by a long shot.
2) Making a fuss over the distinction of m/s^2 versus N/kg is not sufficient to solve problem (B), let alone problem (A).
There is more to physics than dimensional analysis.
