Assess inputs interpolation design

Problem

We would like to learn about the template design of the interpolation ($[[ inputs.the_input_id ]]) whether we made a good decision to follow the YAML-level interpolation (based on parsed structure) instead of text-level interpolation (where we process text first, and parse it next).
