Id links
org-roam v2 uses id links exclusively, and org-braindump template supports that.
You can annotate any headline or file with an id:
* My headline
:PROPERTIES:
:ID: 13e0b822-80a1-4faa-8e13-e768e8cecb65
:END:
and then use this id in links across your braindump:
link to [[id:13e0b822-80a1-4faa-8e13-e768e8cecb65][My headline]]
