The problem with Terraform is that you often need a pinned version because accidentally updating your state file can be dangerous. (Though in fairness, updating Terraform is significantly less troublesome than it was in the pre-1.0 days)
> asdf-compatible - rtx is compatible with asdf plugins and .tool-versions files. It can be used as a drop-in replacement.
asdf + direnv makes my work life so much easier. I have one .envrc that checks what branch I'm on and switches you to the right Terraform workspace and sets correct env-vars too.
It's just like how you wouldn't have different people manage the same Python codebase with different package managers. You agree on the standard for that business or project and have every instantiation of that project follow that same standard.
tfenv is also available in homebrew for installing multiple/different versions of terraform
