What would be the point of printing a warning instead of doing just what the user is expecting? Freezing the stdlib is a startup performance optimization. It doesn't need to be turned on when hacking on the Python source code... And having to type "-X frozen_modules=off" is much more of a nuisance than losing 10 ms in startup time (which you won't even notice in most cases).
