Asana doesn’t reveal its roadmap but will update this thread if/when something changes.
Many of us use the existing features of Asana projects, but just make sure to make the permissions default to “Commenter” to tasks are not able to be marked complete. There’s linking, vanity links, levels of hierarchy, etc.
There are integrations which may or may not be helpful (for example Confluence) at Asana Apps and Integrations • Asana.
Thanks,
Larry
