As an engineer, not a mathematician, I'm glad that good mathematicians care about good notation. The relatively-elementary maths that I learnt didn't always have good notation, the tradition seems suited to chalk and pen i.e. complex glyphs are easy, but perhaps because with hand writing the size and position of elements can be ambiguous, too much notation is overloaded and re-used. Even simple stuff like an exponent of -1 meaning inverse function, it's hardly unusual for it to be mixed up with numerical exponents.
One bugbear is that mathematical writing leaks into engineering science. I wouldn't ask professional mathematicians to start caring about units or change their style while communicating amongst themselves, but in my view textbooks ought to define notation before they use it, and clearly define the units used in all expressions.
