Maybe starting this way makes sense. But when the project is trying to compare itself to others, it's only fair to compare based on what's true of the project currently vs what's aspirational. I would guess that for many potential users, the temporary limitations trump most of the stuff in the comparison portion of the FAQ, or the "current shortcomings" section. And the "Getting Started" section could also say "create an account and familiarize yourself with the existing terrastruct product" or whatever.
