Use-cases

When looking at a transform configuration to get our events to conform to ECS I found the need to move the values from several fields to the tags field defined by ECS. As it is a list of keywords, with variable contents, it would be nice to arbitrarily push values into an array with remap.

Attempted Solutions

It would be possible, but very brittle, to use tags[1] = "foo" - however this could overwrite an existing value unintentionally.
