No, it should not. Read TYPO3 Core API [1]:
======================
If defined (even empty), a checkbox is placed before the input field.

If a value other than the value of 'checkbox' (this value) appears in the input-field the checkbox is checked.
======================

The following will remove the checkbox for you:

unset($TCA['pages']['columns']['nav_title']['config']['checkbox']);

-1 on the patch because it breaks compatibility and completely disagrees with TYPO3 Core API.
