Platform missing/package request feature matrix?

["OBATA Akio" <obache%netbsd.org@localhost>]

Hi,

I have ever see, due to missing XXX on NetBSD,
  * cannot packaging YYY
  * cannot update package ZZZ to x.y
  * disabled xxx feature for NNN package

Such platform missing / package request features matrix might be a hint
for improvement points of NetBSD (or pkgsrc).
Where should it be put? Wiki?
