Var file is not applied to init

[autarchprinceps]

Despite running the tofu-plan with a var file setting:

It fails at not having variables set in the initialisation, which is essential for backend configuration dependent on the environment:

Manually running a tofu init -var-file=../vars/preprod.tfvars followed by the same for plan or apply on the other hand works without issue. Paths are correct, I double checked that. I think it just provides the vars to the apply step, which may be enough for some cases, but far from all, and providing it to init doesn't hurt in those either, but failing to do so makes it unusable for anybody configuring something like this example, where different vars point to different state buckets for example, because they are in different accounts, as is best practice.

I assume the same will likely be true for tofu-apply, but as we create a plan first to approve what tofu is going to do, I can't easily test that

This is releated to the Early Evaluation feature in OpenTofu 1.8

Are you planning to support this?
