It is quite simple and in line with other insets:

* Backspace at the first position in the inset converts it to normal
  text (in this case LaTeX code (without beeing marked as ERT))
  
Now edit ...
  
* Highlight and Ctrl-M converts it back to a Math inset.

If all you want is simple editing, there is no urgent need to have it as ERT
in the meantime.

OK, I see 2 advantages:

1. no need to place the cursor or highlight

2. you can compile while the Math is editible (as ERT)

that might offset the cost of added complexity.
