   ### Question
   
   The documentation states that metadata tables can be queried with `TIMESTAMP 
AS OF` and `VERSION AS OF`. As tables can be queried for a branch or tag using 
`VERSION AS OF` as well, this suggests that metadata tables can be queried for 
a branch or tag this way too. However, I have found that `VERSION AS OF` seems 
to have an effect on only some metadata tables and not all. E.g., querying the 
`history` table always returns the history of the main branch.
   
   Which metadata tables support querying for a branch or tag (or snapshot for 
that matter)? And which ones do not? For the ones that do not, is it simply 
that the support hasn't been implemented yet? or is there some inherent 
technical reason it is not supported?

   In any case, it would be helpful to document the current state of support.
