It would be nice to be able to use JavaScript arrays and typed arrays
indistinguishably when calling native functions.  Rather than each API
defining separate entry points, having float[] imply that Float32Array is
allowed would help that, if that can be done in a way that doesn't make
implementing optimized versions for typed arrays hard.

That implies implementation work for any API taking numeric arrays.  I
don't know how many others exist that would be affected by that (if any).
