That sounds more like an argument to seal your classes, rather than for why the JIT doesn't, in addition to that, assume classes as sealed until proved otherwise.

You're talking about the programming model, where I'm talking about the implementation.

Well, JIT heuristics end up being designed to live with the typical code patterns of the programming language.

In Java's case, since methods are virtual by default so with open classes a large majority of the code has a possible indirection, hence such optimizations.
