I don't think any other name would make it easier to find this user option.
What is missing is a direct explicit link to the option name.

Then what about using a Help key to display the additional information?

When seeing this yes-no question the user might wonder *why* this question
is asked, and this key will display the Help buffer with explanations
and a link to the corresponding user option.

For instance, query-replace already provides Help keys C-h, f1, ?
for displaying the Help buffer with the information about available keys,
and it adds the hint "(? for help)" for the end of the query-replace prompt.
y-or-n-p could do the same with e.g.

    File is large (11MB), really open? (y or n) (? for help)
