A formula is a way of describing a logical structure, as opposed to a picture, which describes a graphical structure (even though one may use formulas to create pictures), so in this sense a music sheet can be viewed as a formula, for example. So formulas are in much wider use that in just math, and it is good for LaTeX, or any documentprocessing system, to support that, mainly because it is costly not having the author entering the formulas. So the ideal for the author, is probably to quickly output the semantic contents, and it should be possible to somehow enter the other stuff independently of this (also so that it is possible to choose a suitable degree of integration of the involved processes).
