You don't use bit manipulation in (idiomatic) Java, you use EnumSets 
(use case 1) or one of the various infinite-digits math libraries (use 
case 2).
I have yet to see a third use case, and there's already libraries for 
these, so I do not see a problem.

All of which, of course, just elaborates the point you were making 
around this paragraph: Each language lives in its own niche, and when 
coming from a different niche one usually sees all kinds of problems but 
has yet to encounter the solutions.
