Primed Variables in Mathematica

Primed variables are in such common use in textbooks and papers that I don't understand why Mathematica doesn't allow them.

Of course, x' represents a derivative, but there is a prime character that can be obtained by esc ' esc or by \[Prime]. 

x\[Prime] // Head
Symbol

But the problem is that the \[Prime] character is not raised but sits at the same level as x. It would be much better if the \[Prime] character were raised to the normal level to give better looking expressions. I admit that there could be some visual confusion, but not Mathematica confusion, with derivatives, but it would usually be clear from context.

I wish that WRI would fix the Prime, DoublePrime, ReversePrime and ReverseDoublePrime characters so they displayed at the correct vertical level in expressions.
