What things would that be? The only ones I can think of are raw bytes and some 
control characters.

The only reason why C-x = shows octal is inertia. If you wrote the command 
today, you would not include octal.

This is just another Immovable Ladder in Emacs. It must be preserved exactly as 
it is, for the sole reason that it has always been this way.

Or perhaps we could improve the more commonly used and accessible `C-x =` to 
show both?

I could write a patch to change it (with an option to keep the Good Old Times 
look for the traditionalist), but there's no point if it would be dismissed out 
of hand. Would it?
