Let's not underestimate the advantage of this point. Currently, 
Bugzilla's default field set includes some fields which most people 
don't use (e.g. URL). It would be great if the custom fields schema were 
such that we could easily transition fields from "hard-coded default" to 
"shipped-enabled custom", so people could remove them easily.
