Yes that would help somewhat

Here is a small example flow using nested flow variable references without relying on any fully recursive renders:

id: flow-variable-example
namespace: company.team

inputs:
  - id: date
    type: DATETIME
    required: false

  - id: user
    type: STRING
    defaults: Rick

variables:
  date_raw: "{{ inputs.date ?? execution.startDate }}"
  day_of_week: "{{ render(vars.date_raw, false) | date('EEEE') }}"
  full_date: "{{ render(vars.day_of_week, false) }}, {{ render(vars.date_raw, false) | date('yyyy-MM-dd') }}"
  greeting: "Hello, {{ inputs.user }} on {{ render(vars.full_date, false) }}"

tasks:
  - id: hello
    type: io.kestra.core.tasks.log.Log
    message: "{{render(vars.greeting, false)}}"

@acmaste we can consider adding a renderOnce() function, which would be equivalent to render(vars.your_var, false) but less verbose. Would that help?
