this is similar to other opencore debacles, Hashicorp wants you to use their managed Terraform rather than someone else's integration. This means that if you choose TF today for you managing your IaC you'll potentially be locked into using Hashi products down the road. The community is all but guaranteed to fork TF which means that over time the two forks will diverge and you'll have a bad time when trying to read docs, debug, contribute fixes.
