Emm .. no. It is not mainstream. Multi-cloud may be forced choice for some regulated fintech, but no sane project will double the infra codebase just to get from "lock-in". I see no other benefits. And double the codebase is quadruple the bugs. This is main Terraform's sales pitch, and it has to die. IMHO.
