Sure.  As is using printing letters instead of hand-made calligraphy.
It makes for a consistent stencil quality.  But we don't have stencil
quality problems.  Your argument may be that it somehow helps if
identical meaning is conveyed by identical shapes.  But if that were
actually the case, we would not need optical correction.  In fact, the
most common _deficiency_ of computer music typesetting is that the
computer overuses mathematically "correct" identical shapes and

Calculating a shape does not even involve a run-time _choice_ (choices
are, in my opinion, discrete), so no, this does not simplify things.
