Does Ember Data call findMany? Can we?

I’m wondering whether to implement REST endpoints to support the findMany RESTAdapter method, but it doesn’t look like Ember Data ever calls this, except to load records for hasMany (async: true) relationships. Is this the only case where Ember Data will call the findMany method of the adapter? producing a request like /endpoint?ids[]=1&ids[]=2 if using the RESTAdapter.
