Is the use of proper time just for ease of simple equations? ie you could define velocity and acceleration with any reference time you want but all other choices are arbitrary other than proper time- proper time is the only time that is special.
It seems to me that if you use proper time then you are able to shift all of the transformation machinery over to spatial components- ie when you see partial derivatives appearing you know they are tied to the spatial components and not to the time part.
To put it another way - If you picked a time other proper time you would see partial derivatives floating around that might have to do with time or/and might have to do with spatial components.
