A big gap with native is dependable storage for applications. I started sketching the problem space on this wiki page:
https://wiki.whatwg.org/wiki/Storage Feedback I got is that having some kind of allotted quota is useful for applications. That way they know how much they can put away. However, this clashes a bit with offering something that is competitive with native. We can't really ask the user to divide up their storage. And yet when the user asks an application to store e.g. a whole bunch of music offline we don't really want the user agent to get in the way if the user already granted persistence. -- https://annevankesteren.nl/
