 ### Why not native Terraform Backend
 
-Unfortunately, Terraform Backends is not pluggable like Providers are, see https://github.com/hashicorp/terraform/issues/5877.

-Due to this, I couldn't make a proper native Terraform backend implementation for Git, it should have been implemented and added to https://github.com/hashicorp/terraform code base. There is an open ticket to do it https://github.com/hashicorp/terraform/issues/24603, but it is unclear when this would happen ([if it will at all](https://github.com/hashicorp/terraform/issues/24603#issuecomment-613533258)). That said I figured this HTTP backend implementation might be useful for the time being.
