> Env variables should be a solved problem I think the main problem is that this problem is 99% solved by the shell alone. Shells are very versatile and it is quite easy to setup different environments using your shell. I'd bet that the crossover of people good at manipulating environments on workstations and people good with shells is pretty big. That is, the people with good domain knowledge have little motivation to write tools to address this.
