C-<number> is bound to `digit-argument' in Emacs, and many users
(including myself) are used to insert prefix-arguments using these
bindings (instead of going through C-u, although evil allows to type
prefix-arguments straight ahead without C- keys). Therefore IMHO
overriding this binding may cause a lot of problems and inconveniences
and gain very little. Evil will probably never redefine C-6.

If you really desperately need this binding you can always use

(define-key evil-motion-state-map (kbd "C-6") 'evil-buffer)

in your .emacs file to redefine the binding on your own.
