Is it possible now or can this be a feature request to allow the deletion of multiple files in one request.?
It is not possible now. With the changes to the system we are about to introduce, it would be possible for someone to build and offer an extension that provides such API.
Can this functionality be apart of a API function in the future after the next release?
I am not ruling it out, but I am cannot add it to the roadmap either. I’d like to see if the extension mechanism we’re working would be flexible enough to support that capability.
