absolutely, that's what I said when I talked about strong org support.
also, if you don't have strong org support, you risk getting onboard people that just want to work with that specific technology that WILL gtfo as soon as they need to change team to one that doesn't use it, or if the technology is sunset, etc., so it's even more risky to have an exotic stack in the middle of more common stacks
Most orgs that fail on elixir fail due to management.
