It does matter. What qualifies as missing data?
If a table is missing gets the tag, same with a ship that has no hierarchy in the POF whatsoever...then the tag is worthless. One isn't missing anything at all really, while the other requires you to go back into a modelling program. If they all have the same tag then it's meaningless, because everything will have it.
You could just ignore the table side thing anyway, because not once have I ever used the table that came with the model without heavily editing it. In fact, I recall using an included table as a reference for subsystems only to find out that there were 4 to 5 other ones on the POF (subobject based), that weren't listed and caused FSO to throw errors. If there wasn't a table, I would have checked and it would have saved me more time even. The speeds/maneuverabilities for what I make don't work outside of it, really, so unless you have the same flight model as I do, it is useless to everyone else; I'm not going to re-imagine what something's role should be just so someone MIGHT use it. That's absurd. Including a table is a pointless venture - I wouldn't use one, and I wouldn't trust anyone who would!
Perhaps they should be separated by what you need to use to "fix" it.
ie. its fixable PCS2-side, or you have to bring it back into Blender/Max/Whatever to fix...
But that goes back to the "negative" thing, don't exactly want to call people's hard work bad, you know?
You know what, do whatever you want. I just realize that I don't care I won't use it anyway. Just like how I don't trust anyone to make a bug-free model, I wouldn't trust anyone checking them to catch all the possible faults. Which boils down to the fact that I'll have to examine everything myself anyway.
Well, that was a waste of time and words. Sorry for wasting yours.
tl;dr **** it what do I care
