You should also be able to use fromIntegral to convert from Offsets to
arbitrary numeric types.

Yes, when factoring out biocore, we decided to make newtypes for various
types in order to improve type safety. I'm not 100% sure this is always
the right thing to do, sometimes fast and loose is what works best - but
in general it's better to err on the side of safety.
