That magic will surely prove to be problematic. I see lots of potential issues. It automatically installs other Hashicorp tools, presumably outside of your system's package manager, which means that it is a package manager in addition to whatever else it does. Where does it install software? How does it verify integrity? Does it build from source or use pre-built binaries? If they are pre-built binaries, how do I get the corresponding source code and build scripts? Does it bundle all other dependencies? How do I make sure I get security patches for the whole dependency tree? I don't expect that Hashicorp would have satisfactory answers to all these questions. Furthermore, automatic dependency installation sounds like it will make reproducibility difficult, and I imagine automatic application type detection will fail in spectacular ways. What happens when the magic doesn't work? The Appfile looks like yet another ad-hoc domain specific language that you need to learn that has the usual major deficiencies compared with using an existing general purpose programming language.
