Insomuch as the LDS Church is an organization, to maintain its integrity it must manage itself as an organization. This means establishing and maintaining protocol. The church places consistency as a high priority. Unlike McDonalds, where in India you can't buy a cheeseburger because of the culture, the church usually tries to keep protocol and doctrine consistent across cultures, lands and languages. Thus we end up with these protocols that are regarded as doctrine but whose purpose is to merely maintain consistency and avoid organizational drifts.
There is of course no spiritual danger in recording any blessing or ordinance. When the church creates a logistical or operational policy (e.g. no recording blessings), it does so to maintain its ability to meet its purpose on a worldwide level. Many such policies are concessions that must be made to conform to an imperfect world, such as was the abolition of polygamy (at least these were the reasons given over the pulpit).
I think the important thing is to remember that while the church is directed by the Lord, it is not an intermediary for us with the Lord. It is a resource we have to draw closer to the Lord. If I feel inspired to record or write down a blessing (which practices are in harmony with the principles of revelation), I'll do so. I hope these opinions are helpful and provide some insight to the other participants of this thread.
