If what you mean lines up with

  1) in some areas, CDP boundaries actually have some relevance, and people
  know where they are and use for things.  In those areas it makes sense
  to have them in OSM.

  2) in some areas, CDP boundaries are merely for the census, not
  understood or known about by more than a handful of government people,
  and have almost no real-world relevance.  In those areas the CDP
  boundaries shouldn't be in OSM.

then it sounds good to me. I live in a type 2 area, where every bit of
land is in both a city/town and a county.  (I realize that in Alaska
there are some areas where CDPs seem to matter.)
