Another (but different) question about 4.1.2

I recall that the deliberations on 4.1.2 were quite well considered.  Some of the nuances, however, have become fogged in my memory.  Do we have notes in the wiki/boneyard or elsewhere on its crafting?  URLs, better recollection, or deeper understanding are all welcome.  Thanks!

Specifically:  Why, in the first phrase of 4.1.2, is it just name/role, and not name/role/states/properties/values?  It seems to me that read-only states/properties/values are often presented visually, and in those situations the information is important to make available to assistive technology.

Follows is 4.1.2, with the bits that now strike me as missing between INSert tags.  (The grammar is a bit off with the insertion, but marking that up would just make it less readable for the moment.)

4.1.2 Name, Role, Value:  For all user interface components (including but not limited to: form elements, links and components generated by scripts), the name and role <INS>and states, properties and values</INS> can be programmatically determined; states, properties, and values that can be set by the user can be programmatically set; and notification of changes to these items is available to user agents, including assistive technologies.
