I agree under the assumption that such resources exist.

Or the recommended extension point for custom resources that are
resolvable to local files.

Would work and it would even be pretty easy to retrofit the
implementation of isFilesystemOnly to look after that interface
instead of the FileResource class.  Same for task that only work on
FileResources right now.
