To add a couple of points from the release management point of view: If 
these and other schema changes are important for general schema 
enhancements, now (i.e. major release) is the best time to introduce 
them. Otherwise, as per our release policies, no backwards incompatible 
schema changes will be made until the next major release.

Also, it is best to modify schema in a consistent manner across all 
services included in a release instead of just a few.
