If you ever had to customise Profile Properties in the Shared Services Provider, you'll know what a royal PITA it is to migrate the properties from one SSP to another (especially in a Staging environment). Typically, you would either backup and restore the SSP, or recreate the Profile properties from scratch. With the latter you would have the problem of possibly not recreating the properties identically to the latest version.
