The mentioned specifications require that conforming decoders output frames (that may contain interlacing artefacts), this is independent from the used encoding method (some codecs allow field encoding - but the decoder has to output frames for such streams). I believe the main reason is that no displays exist (anymore) that can display fields. Above is not necessarily true for hevc, FFmpeg does not support hevc interlaced decoding though.
