I'm not an user of the filter, so can't say even what is useful
for. Can someone comment on it?

Is it possible emulate it with the native filters?

>From mplayer:

  ilpack=mode

  When interlaced video is stored in YUV 4:2:0 formats, chroma
  interlacing does not line up properly due to vertical downsampling
  of the chroma channels.  This filter packs the planar 4:2:0 data
  into YUY2 (4:2:2) format with the chroma lines in their proper
  locations, so that in any given scanline, the luma and chroma data
  both come from the same field.
                 <mode>
                      Select the sampling mode.
                         0: nearest-neighbor sampling, fast but incorrect
                         1: linear interpolation (default)
