You are asking for the impossible.  I could quantify this complexity
today, but that would tell us very little about the future.  I cannot
peer into the future, inspect all plausible evolutionary timelines of
the Java SE Platform, and come back to you with any kind of measurement
of the potential long-term impact of these additional methods.

What I can do is apply my judgement and experience, together with that
of engineers who have vastly more experience than I -- or you -- in the
implementation of high-performance, production-quality JVMs.

You are free to disagree with the conclusion that I have reached by this
method, but that does not mean that rational discussion is not possible.
