I'd be tempted to challenge this assertion. It made sense when handwriting to maximize for not having to spend too much time writing, but with modern auto-complete, I might start to believe that it be clearer to use the long form for everyone, yes even for a person familiar with mathematics. If all math was rewritten long form, I feel it would honestly have second order effect on approachability and being able to understand papers even from other mathematicians.
