Before I go and make a fool of myself, how silly would it be to use Infracost with 3rd party providers, specifically:

terraform {
  required_providers {
    confluent = {
      source  = "confluentinc/confluent"
      version = "1.3.0"
    }
  }
}

I’m a bit rusty with Golang, but if its not too silly, I’m prepared to create a card and have a go with it.

Hello @best-apartment-84744! It won't be silly at all, but it could become a challenging task both for you implementing it and for us supporting it. 🙂 This is the sort of thing we'd love to support longer term but our team is currently focused on supporting AWS, Azure and GCP so we prefer not to work on new vendors at this time. We would like to move towards a provider model where community-supported cloud vendors could also be added (similar to Terraform providers). You can also create a new issue in Infracost repo, so other community members could follow it and upvote.

Thanks for the feedback Vadim, I will have a look at the existing cards, it makes sense to familiarise myself with the code base and tackle a simple card first and see how I go with that.
