The cost of bounds checks, which is already low, could be reduced further the vast majority of uses with even more enhancements to the compiler's inlining decisions, so we're talking about an API whose value is already small and constantly declining. However, those who think they absolutely need to avoid bounds checks could, indeed, use a flag to access the JDK's internals. We don't think that such a small benefit (especially when integrated over all users) merits a supported API.
