Quite straightforward implementation -- all the conversion magic is happening in IMB_exr_write_channels() and remained changes are only needed to pass information whether channels is to be converted to half float or not. Regular file output will use full-float for Z pass, which matches behavior of the single layer EXR files. But when saving happens with File Output node then all the passes are respecting half float settings because it's not possible to distinguish whether we're saving Z pass or not.
