If the maintainers can keep a good throughout of pull request approvals, I think there’s a good likelihood that OpenTF could outpace Terraform in capability. Terraform, IMO, has benefitted significantly from having some very smart people at the helm. Most recently I’ve been impressed with the declarative mapping of imperative actions including import, state moves, and more. These things required very carefully coordination, especially in large active configurations, and are now quite simple and safe.
One has to wonder how much collaboration was prevented by having Hashicorp refuse to hear their users or accept PRs. At some point, opensource or not, people just stop bothering.
A year ago most people probably wouldn't have known or cared about a small new fork and I don't think it would have gotten the community support OpenTF has now.
Was thinking the same. Would be great if they provided more "experimental" features with a flag or ENV. Then the default cli could be the "comparability mode". Cheers and good luck to the project!
