Hi all,

Since updating the org-id code [1] to use the standard org-link registered functions instead of hard-coding org-id opening, I have a problem using org-roam.

org-roam overwrites the :follow function for "id" links from the build-in `org-id-open' to its own `org-roam-id-open' (https://github.com/org-roam/org-roam/blob/8667e441876cd2583fbf7282a65796ea149f0e5f/org-roam-id.el#L91).  The only change between these functions is to insert a call to try `org-roam-id-find' before trying `org-id-find', which uses org-roam's cached sqlite database to find the id (https://github.com/org-roam/org-roam/blob/8667e441876cd2583fbf7282a65796ea149f0e5f/org-roam-id.el#L70-L71)

As well as being messy, my specific problem is that the improvements to open search strings in org-id links are no longer enabled when org-roam is loaded.

It seems reasonable that a library might want to provide its own way of locating org-ids.  The attached patch adds a new hook variable `org-id-find-functions` which contains functions doing the same job as `org-id-find' that should be tried first.  Then all org-roam needs to do is add its `org-roam-id-find' to the hook.

Does this seem like a good idea?

Thanks,
Rick
