Proposal to remove Preferred-Value field for region YU in LTRU

Can someone explain to me what the stability policy is for codes with
respect to preferred values?
Historically, it was a concern that codes might change.
If I use the registry to choose the preferred value for a region, and that
preferred value can change, then isn't it tantamount to the code changing?
If I had data that would be represented by YU/CS and after the preferred
value is removed it should instead be YU, that seems like a problem.
Especially since the relationship between CS and YU becomes lost.
Also, it may not be clear which CS records should be restored to YU.
I don't see that the fact that the target preferred value of YU is also
deprecated is a good reason to break the relationship at this point. We
still end up with deprecated codes with no preferred value to go to, so why
introduce an unnecessary change?
