I happened onto Poser halfway through the P6 era, and bought my first PC.  Imagine!  Being able to do 3D right at home!  One of my irritated questions was why the MATs were in the pose library when there sits a purpose-built material library, lonely and unused.

     One of the grizzled vets explained that the MATpose was an inspired hack hailing from the P4/ProPack days.  It was a brilliant solution, and I can understand that the use of the MATpose was retained for backward compatibility for a while, but its day has passed.

     As for vendor concerns, if someone won't/can't spend the money to upgrade since P4/PP, they aren't likely to spend much buying content either.
