policy_tags variables are replaced by their value

[thibaultam]

Many thanks for this great project, it's super useful.

We have a little issue though. We use policy tags on columns to identify sensible data (PII). To make this more visible we use a variable defined in dbt_project.yml:

# 
vars:
  policy_tag_pii: projects/our_project/locations/eu/taxonomies/6552354571455331948/policyTags/6569849934623492533

We then use it in model.yml like this:

columns:
  - name: email
    policy_tags:
    - "{{ var('policy_tag_pii') }}"

We consider this to be more readable.

The issue I have is that dbt-osmosis yaml generate will replace this "{{ var('policy_tag_pii') }}" by the corresponding value.

Is there a way to avoid that behaviour in the current way of things?
I'd be happy to contribute if you think that's something that should be included. Any guidance about where this replacement happens would be appreciated.
Thanks
