I agree with both of your comments, I've noticed exactly the same thing. Every feature that fix something brings more complexity and have probability that will not interact nicely with some other features which means you need to make another feature that will fix that and then that feature... Soon people will use different dialects of the language like in C++ and like in C++ only few will be able to say that they really know the language. How will managing huge enterprise projects will look like in future? With average developers maintaining it and not language experts like in case of Mozilla Servo? Time will tell I suppose. I am little bit pessimistic but I hope to be proven wrong.
