With OAuth2 you could essentially take an existing WordPress website and easily build out a React Native App and not have to worry about the data structure or setting up a service like Firebase. This could allow devs to move quickly on small apps that extend the service already being provided on their WordPress site.

For example: If you have a client that is a Property Management company. They might collect rent through their WordPress site. Now they could easily move that effort into a React Native Expo app which could provide that basic functionality that a small business would need.

I'm not proposing that this is going to be something you would want to do for larger scale apps but for the small business owner this could be very beneficial.

Also, for anyone who will say that the database won't scale check out HyperDB or LudacrisDB because sharding is real in WordPress land. WordPress.com has 5 million tables or something crazy like that and they've distributed that load through replication. This is very easy today and could give you the power you need when building and scaling a native app.

What do you think?
