Shipped to First Release: Flow integration for SharePoint document libraries

It's a little confusing that the list of Flow templates is completely different after clicking on "create a flow", depending on whether or not a file was selected. If a file was selected, then the trigger is a "requst/response" that posts to Azure and returns the item ID and file url. If a file was not selected when clicking on "create a flow", then the trigger varies based on the selected template, but one option is the "when a file is created". This trigger is known to have significant shortcomings as it lacks the ability to access SharePoint metadata. So, we are left with two scenarios:

1. Create a flow that has access to metadata, but has to be manually triggered by users.

2. Create a flow that starts automatically, but has no access to metadata. 

I'd guess that most shops building workflows will want access to both of the above, the ability to start a workflow automatically as well as the ability to access metadata. 

I see that it was said that accessing metadata from a library-based flow is a feature that was being worked on. Is the current variation what was referenced? Or are there plans to support accessing metadata from automatically started Flows?
