New Library UI - non-required "Required" metadata

Bumping this topic, as it remains a major roadblock to businesses like ours adopting SP Online.  I did discover a minor improvement - modern library experience does now pop open the details pane when a document is uploaded that requires metadata.  However, the user can simply click anywhere and then there is no indication that the document is incomplete.  Other issues mentioned previously are still unresolved. 

Mark-Kashman  danholme, can you or someone from the team confirm issues with required metadata are being worked on to make this viable solution for businesses that rely on metadata?  

I did some additional testing with content types.  In addition to the issues listed in the original post, such as not prompting for content type selection on upload, I noticed odd behavior of required fields Assume a document is uploaded and the default content type has a field that requires metadata.  If the user changes the content type, the information pane continues to display the "Missing required information" for the original content type.  If a new content type is selected, the user should not need to fill in metadata for the original content type.
