Yes, that's mostly covered by the companies sponsoring OpenTofu's development: Spacelift[0] (I work here), env0[1], Scalr[2], Harness[3], Gruntworks[4].

By the way, the reason I singled-out Spacelift is due to its quality, and the great Terraform provider it has. Scalr [3], for example, has a really low-quality Terraform provider. I extensively use the hashicorp/tfe provider to manage TFC itself.
