Probably asking the obvious, but why can't you just write:
headers.firstValue(name).orElse(defaultValue)
instead of
headers.firstValueOrDefault(name, defaultValue) ?
I'm not sure the value provided by introducing these methods is worth the
increase in this API's size. Optionals provide a toolset for such tasks.
This toolset is much richer than just "defaulting".
