Hi LuxSpecs,

We wouldn't call it an "omission" as much as a "design choice"... :-)

We don't cache this data on the client because, in the general case,  
we can't detect that it's statically cacheable.  (e.g. your code may  
be filtering this list the second time around based on other  
selections on the page or other changes in server-side state).  In  
practice we have not found this to be a significant issue in  
application responsiveness or user experience.

That last part is exactly the issue: we don't want your programming  
burdened with needing to "tell it to do so" -- this leads to a lot  
more code and a lot more opportunities for errors.

Thanks!
