Exactly.  My request is almost exactly as you worded it, but in reverse: 
  rather than adding the info obtainable from the universally-supported 
"the properties" to something widget-specific, I'm suggesting the engine 
have an enhancement to add the widget-specific info to the 
universally-supported "the properties" info.

This suggestion would seem to address hh's concern as well:

By having an engine-level enhancement to include the values already 
supplied by the widget per the widget spec included in the existing "the 
properties" function, we would then have one universal array to work 
with which would adequately describe any object with no additional work 
needed from any widget developer.

Consider the LC IDE's Inspector:  to populate its controls it obtains 
"the properties" from all LC-native objects, and "the properties" + 
widget-specific info from widgets.

If the engine included the widget-specific info in "the properties", the 
Inspector need only query one place to obtain all relevant info about an 
object.

And given that "the properties" was introduced to provide a universal 
way of obtaining object info, and that widgets were introduced as a way 
to provide native-like objects without requiring engine-level 
implementation, honoring the purpose of "the properties" by extending it 
to include widget-specific info would seem every bit as useful as having 
"the properties" has been until the introduction of widgets.
