Describe the feature:

It would be cool if GET /_tasks/<taskid> could support a list of task ids (i.e., comma separated or as a request body).

My use case here is to avoid using the detailed parameter together with the actions parameter, which may cause detailed information to be gathered for quite a few running tasks, which according to the docs can be expensive. So I'd like to target the detailed usage to just a specific subset of tasks. Rather than issuing a request per tasks, I'd like to issue a single request with a list of tasks.
