I've found the internal `without_transaction_enrollment` callbacks which have not been newly used over five years, when I tried to work reverting #9068 (https://github.com/rails/rails/pull/36049#issuecomment-487318060). I think that we will never make that callbacks public, since the mechanism of `without_transaction_enrollment` is too implementation specific, at least before #9068, records in a transaction had enrolled all into the transaction. That callbacks was introduced at #18936 to make `touch_later` #19324, but I think that the internal callbacks is overkill to just make the `touch_later` only, and invoking the extra callbacks also have a little overhead even if we haven't used that. So I think we can remove the internal callbacks for now, until we will come up with a good use for that callbacks.
