This is a great point, previously the tradeoff was build in python in 2 weeks versus 2 months and even if your app performance is worse you built it faster and maintain it more easily. Now I am wondering, for all the devs who do not have experience in Rust, can they still maintain the code when the usage limits get hit? Since there is an automated test suite and easily verifiable results, this is a good area where you can be assured the compiler is working properly; however, if new features need to be added, I'm not sure how easy it will be for them.
