I actually do like the 'explore backlinks' pane for Foam so it would be of some navigational use for me. They list reasons for adding it as:

> Make every link two-way navigable in published sites

> Make Foam notes more portable to different apps and long-term storage

(via https://foambubble.github.io/foam/materialized-backlinks)

Though I may be getting confused between the backlink differences that Foam, Obsidian, and Roam offer. A list of forward links per document would actually be useful as well, which IIRC neither Foam or Obsidian offer at the moment. Obsidian also shows the user 'unlinked mentions' along with explicit backlinks, which is also a nice feature that Foam lacks.
