Value usage in Sensor data filters

[dbeilin]

I have a question regarding data filters.
I created the following Sensor:

apiVersion: argoproj.io/v1alpha1
kind: Sensor
metadata:
  name: github-pr-comment
spec:
  template:
    serviceAccountName: argo-workflows-server
  dependencies:
    - name: pr-comment-dep
      eventSourceName: github-argo-event-source
      eventName: pr-comment-trigger
      filters:
        data:
          - path: headers.X-Github-Event
            type: string
            value:
              - issue_comment
          - path: body.comment.body
            type: string
            value:
              - "/test"

I've set body.comment.body to trigger on /test but noticed that it also works with anything else following that /test (i.e /test <some-other-string> would also trigger this Sensor).
I'm wondering if I should have used template instead of value along with some sprig.contains() for example, or what would be the best practice in this use case? Is there any scenario where value's behavior of catching /test <some-string> changes in the future?

Thanks :)
