I've been watching this thread, trying to determine if any new functionality 
would need to be added to bookmark.el in order to support EWW bookmarks.

So far, it looks like it can all be implemented using existing functionality in 
bookmark.el, using `bookmark-make-record-function' and a handler function, as 
per above.

If it turns out that anything new is needed, please say so.  bookmark.el should 
be able to supply generic bookmarking functionality to other packages, and I'm 
happy to help with that if further extension is needed.

Best regards,
