[wp-hackers] WordPress API Enhancements

[Daniel Jalkut]

I only recently discovered the WordPress API enhancements that are  
being added for 2.2 to the xmlrpc.php implementation. It looks like  
this changeset is where the bulk of the functionality was added:

http://trac.wordpress.org/changeset/4793

But I don't see an associated ticket, or any clues as to where I can  
read up on the reasoning that went into these changes.

In particular I'd like to know if there was a debate around whether  
to invent the extensions instead of taking a Drupal-like approach and  
overloading "blog ID" to refer to the various asset types on the system.

For example in Drupal the "pages" can be accessed using the usual  
MovableType API, as long as you specify "page" as the blog ID.

Is there a mail thread, or Trac ticket discussion, where the details  
of this implementation were ironed out? I'd like to get the  
background story if it exists. In the meantime I'm going to report a  
couple issues for the record that might invite some discussion (if  
late, sorry).
