I prefer to link my sites organically inside of text in the page. E.g. on a page about Linux I'd write
GNU/Linux is an [operating system](../os) based on the Linux [Kernel](../kernel).
Tada, two backlinks without having to list them. If there's no link on the page it's not important.
Do you see problems with that approach?

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.
