No, it does not. If it did, there would be no discussion because it would just work. It decodes it like a progressive half-height video. It decodes any other interlaced format as weaved fields into one frame and exports metadata about interlaced status and field order, which is required for both software and hardware deinterlacing. It does not do that for HEVC. Hence, it is not supported. There will be no manual hackery for HEVC interlaced, or trying to get separate fields to work. Either it adopts standard decoding, or it won't be supported.
PS:
Just because something is theoretically valid in DirectShow, it does not mean that it would actually be supported by whatever renderer one cares about.
