That's fine; I'm not sure of that either.  I have no particular opinion 
on that question, in fact.

This is a price of early adoption, sure.

That's true, but it's not a given that we want this content to 
interoperate as-is.  Early adopters of known in-flux technologies 
typically realize that they might have to make changes; if a different 
data storage API is decided on, or if the subset of SQL that's decided 
on doesn't match what these apps are using, then they'll need to change.

So while I agree that it might be difficult for Webkit to remove the SQL 
support it shipped as soon as some other approach is decided on (if that 
even happens), it doesn't follow that other UAs would need to ship SQL 
support at that point.

There are strong arguments for not breaking existing content, of course, 
but there are also strong arguments for not having experimental 
implementations of early drafts completely dictate the standardization 
process.

No opinion on your other points; this is far from my area of expertise.
