Comment (by kierank):
It can't be fixed in swscale directly because swscale has no concept of
interlaced video - as you say it assumes chroma is associated with the
nearest line. vf_scale is a wrapper that basically calls swscale twice for
interlaced video, one call per field - this is the simplest fix by far.
