We have largely removed support for file-based configuration (eg mappings, settings, index templates) in favour of storing this info in the cluster.

For scripts and mustache templates, we allow them to be passed inline or to be stored in the cluster state. We used to be concerned about locking down scripts in Groovy etc, but with Painless we have safe scripting. Are file based scripts now redundant?

The one upside of files is that scripts can be written with new lines and formatting, while with inline/stored scripts they have to be passed in in a single line of JSON with newlines escaped. However this could be solved by improving Console to do the multi->single line conversion automatically.

Any other reasons for keeping file scripts?
