Hello.

The reasoning behind considering using auto-fill the same as using helper is that if auto-fill is used, it may reveal cells where only a singe option is available, thus giving away (potentially) parts of the solution "for free".

The counter argument is that finding these cells is merely an exercise in word-search, or in this case - digit search, and does not require application of logic, and as such does nothing more than eliminate "manual labor" from puzzle solving.

What do you think? Should it be considered equivalent to using helper or not?
