Prior to Modern Pages, we used to connect web parts to send data from one part to another. E.g., select a document from a document library and display a preview of it in a Page Viewer web part. It's so annoying that SharePoint no longer has that feature. Modern Pages seem to be less Modern than they should be. It's like a beginner's web page instead of something you can actually do real work in.
You should be happy to hear that we are working on this capability and it’s already supported with 3rd party web parts. More details will be released using our guidance and social media channels during the first quarter of 2019.
