Re: Let's turn WebDatabase into a WG Note

I'm not sure that further back-and-forth on this topic is useful at  
this time. I know that you are strongly against Web Database. You have  
expressed that view for some time, and I don't expect to change your  
mind. I don't find your arguments particularly persuasive either. If  
we continue this debate, then doubtless we will rehash points that  
have already been discussed to death.

(If, contrary to my expectation, the rest of the Working Group would  
like to see more of this discussion, then please let me know, and I'll  
be glad to reply to Nikunj's points in exacting detail.)

Further: if the other vendors planning to ship Web Database  
implementations (Google, Opera, perhaps others who have not spoken up  
yet) take the position that they would be like to end work on Web  
Database at the W3C, then I'm fine with publishing it as a Note (and  
possibly continuing work as a WHATWG or webkit.org spec). Until then,  
I would prefer to see work continue here.
