If we convert the output to yuv420p16, we'd need to downconvert it again
when doing e.g. prediction.

Maybe we could output yuv420p16 with avctx->bits_per_raw_sample and use
the value of avctx->bits_per_raw_sample to do the conversion in swscale
instead. However, in this case the pixfmt wouldn't be self-contained.
