So why in this case do we have a constant and a 4*pi? Its because the
electric field is so prevalent as the quantity to study in
electrodynamics, and electric fields find their source in charges via
Gauss' Law.
It all depends on *which version* (the local differential versions or the
integrated bulk versions) of the laws of electromagnetism whose
appearance you are most interested in simplifying.
