This is a great point and something to consider when designing runtime programmable tools. It should mean moving slow, cautious with minimal surface area and opinions about the future is probably a way to go. Having strong isolation is probably good too. This is something that made me uneasy about highly programmable/hackable platforms. I like when the core maintainers understand _how_ a system wants to be extended and shaped and provides precise hooks for doing so.
