Thinking more about this, I think we should modify the checkstyle to not
force us to remove such `final` keywords. While being redundant in the current
"snapshot" of the code, they may not be redundant in the future. I think there
is a big upside of writing code in a "future proof" way.
The modifiers in this class are a good example of that - the JIT
friendlyness of the methods is so important that they should not be affected by
future changes the class hierarchy.
