Node do allow you to declare what node version supported in your package.json. The definition is there, but there isn't any tool that read the declaration and switch to it accordingly. I feel it is somewhat half-assed. But is could also caused by the fact the entity that distribute the package (npm) and node binaries (various of linux repository) isn't the same group of people. So there isn't really anyone can do anything about it unless we get something like corepack someday. (probably someone should name it 'corenode' ?)
