Dropping a value is significantly harder because that value could be in use.

I'm certain there's a really good reason adding new values isn't allowed 
inside of a transaction. It's probably documented in the code.

To answer your question about "what goes into a release", there's really 
no process for that. What goes into a release is what someone was 
interested enough in to get community approval for the idea, write the 
patch, and shepard the patch through the review process. So if you want 
these features added, you need to either: do it yourself, convince 
someone else to do it for free, or pay someone to do it for you.
