Matt, 

Due to “other tasks” I personally haven’t been able yet to follow everything 
that’s going on, nor had I have a chance to look at the POC you and Puspendu 
have created, so I think global update of the page would be too early at the 
moment as it doesn’t really capture all of the concerns and there are certainly 
quite a few vey common concerns that need to be addressed outside of what I was 
able to extract from recent interaction. 
I will do my best to go through all the comments by the end of next week.

Cheers
Oleg
