I can understand the frustration; you aren't the only member that has run into that. Admin has asked repeatedly the when checklists are uploaded that the entire checklist get loaded at once. As for the printing plates, one of the issues ran into is whether they were legitimately issued or if they were backdoored. Confirmed issued in packs, they get listed. However, after many of the 90s manufacturers went bankrupt a lot of unreleased product hit the street illegitimately. That is the fine line being balanced as well.
As for single cards/full sheets, I tend to agree, full sheets should be lsited. I know that there are many items not listed properly here and that is an example. As the site has evolved things that were improperly listed before are getting corrected. My spreadsheets don't lie, what was once listed in one place is now in it's proper location/name. If you haven't done so, PM some of the fine L8s we have here and have a discussion with them. They will happily help out to include good reasoning.
Thomas NNOF is an anomoly because of the Hobby acceptence of this card. While your reasoning is relatively correct, missing ink instead of fol though, because of it's wide acceptence since release it is here as well. If you look search past forum threads, this has come up before.
When the sky is coming down
When you feel like you're going to drown
When you know the end is all that you've been looking for
When the pain is too much to bear
When there's no one who will care
