I'm sure you've heard this before, but if it's not in mainline it does not count. We don't carry code upstream for the sole benefit of out-of-tree users.

This function was merged over four years ago and has never been used in mainline and I doubt a user will suddenly show up in the near future if we were to keep it.
I guess you can just carry one more patch out-of-tree until you can mainline a proper debugfs interface (which should probably not even use this function, as you mentioned yourself).
