IIRC, the reason for this was the following binding in ido file mode:

    (define-key map "\C-v" 'ido-toggle-vc)

If cua-mode is enabled, C-v is processed by cua (as paste), shadowing the
above command.

I guess nobody really uses that specific feature of ido.
I used to use it a lot back when I wrote ido, but never uses it these days.

So the best thing to do would be to remove the above binding - then you
can also remove the setting of cua-inhibit-cua-keys.

Or just remove the setting of cua-inhibit-cua-keys as you suggest; this
effectively makes the other binding a noop if cua-mode is enabled.
