Yeah that sounds awesome to me. It addresses one of the shortcomings of the conventional abstract style which is that nothing is cross referenced - most journals still disallow citations in the abstract

A feature like this would be great for discovering new topics. Right now my approach is to find an interesting paper, and if I need to dig into underlying concepts to really evaluate whether to read in detail then I skip to the lit review and hope for some good bread crumbs, or maybe jump to a fresh GScholar query to do some depth-first-ish graph traversal

It would be really nice to just surf some linked tldrs with high level descriptions of papers and concepts instead!
