Billy Joel would respond that "it seems such a waste of time" because sometimes the BYU clerk often doesn't even hear "I'm movin' out."
You recognized that it's probably easier for you to do that work, but it would be better if you just requested the record in the first place. Let's look at this from the perspective of the BYU bishop:
He's got 100 or so records that are now sitting in his ward and the students are gone. You are asking that his clerk contact all of those students to get their new address information. You also want him to ask if they're living with a parent or other family member so that they can be grouped with the correct household. sbradshaw already pointed out that you will have trouble getting many of the students to answer their phone or reply to an email.
Next, you want him to process an individual move out for everyone who responded, entering the new address and determining the appropriate unit if there are overlay units (YSA ward or conventional ward?) and then making the determination whether they should be in their own household or added to an existing household.
Once he's done with that, he still has to figure out what to do with all of the records he didn't get a response for. Should they be moved back to the prior unit (which may be a different YSA unit at school)? He could try the parents' unit, but that might not be appropriate for some family circumstances. If he wanted to send them to the parents' unit, what if the parents live in different units? What if the parents aren't members of the Church? Perhaps they're living in Orem with Grandma for the summer.
Let's play with some numbers:
- 100 students
- 10 minutes per student to try to get address and parent information
- 50% response rate on new address information
- 4 minutes per student to move the record
- 20 additional minutes per student to try to figure out how to deal with non-responders
- 5 minutes per student to move the record to the next unit or to address unknown
That is over 38 hours of work for the clerk to move those 100 students out. Imagine a full work week spent doing nothing but moving 100 student records. Don't forget to include an hour per night swilling Cherry 7-Up (such a good burn) to drown the sorrows of the day's work.
That is even more complicated in light of the current situation where a large percentage of the students scrambled and moved off campus over the course of a few days. One Sunday, they have church and everything is normal. Seven days later, most of the student population is just gone and church is cancelled. There are a lot of home-ward clerks who haven't thought through the current situation to the point of saying "hey, maybe I should check and see what students' records need to be moved home," leaving the entire burden of getting those records in the right place on the YSA bishops and clerks.
Evan Stephens' proposed solution: "Let us all press on." Don't let those YSA ward clerks steal all of the blessings by doing all of the work.
