I had sort of the same reaction. I just learned a bit of Vagrant recently. I needed something to set up a simple three-node environment for a tutorial I'm doing, and the best starting point happened to be a Vagrant project. It worked well enough that I've been thinking of other uses for it, especially as a basis for automated tests on the distributed system I work on (our current infra for that frankly sucks).
Then I read this, and it doesn't look like it's a Vagrant successor in any way that's useful to me. I don't want it to try and figure out service dependencies for me, because I can absolutely guarantee that it's unable to do that for the component I care about. I don't want it fiddling with DNS. I think using the same description but different commands for dev vs. production is a terrible idea. They say Otto does application-level instead of machine-level configuration, but machine-level is what I want. They say multi-VM is too heavyweight but that's also what I want. It's opinionated in all the wrong ways. Everything in https://ottoproject.io/intro/vagrant-successor.html makes it clear that Otto is fundamentally different from Vagrant, which totally belies their claim (at the end) that it will replace Vagrant in any significant way.
They should just come right out and say that they've created something different on top of Vagrant. Maybe it's cool, but it's not a successor. This brand hijacking just makes them seem fickle or shifty. Now I think I'll just leave Vagrant behind while my investment in it is still small, and learn one of the bazillion other tools that I could use to accomplish the same thing.
