When a race, major or minor, is eliminated, all of its ships, shipyards and starbases defect to the pirate faction.  Some of the starbases are mining strategic resources.  Can the pirates now use these resources to build ships that require the resources?

I ask that question because of something I noticed when I started a game in 0.83 and ran the soak command in the console to let the game run by itself.  Some of the major races and most of the minors were eliminated after a while.  When I was zoomed out on the galaxy map I noticed a pirate ship with a different icon than usual.  When I put the cursor on it I saw it was a Pirate Prototype Bomber that used antimatter.  I then noticed two more.

I thought is was great that the pirates were using the resources to build ships.  It would give even more incentive to quickly destroy any pirate starbases.  However, a few turns later I realized the ships were moving from an area that did not have any pirate shipyards towards an area that did have pirate shipyards.  I also began to wonder about the design of the ships.  This made me think that they were ships from an eliminated AI.  I did some more checking and never saw another pirate prototype ship.  Eventually, I began checking pirate shipyards, and they were all building the standard Pirate Cutter.  Since all pirate starbases and shipyards that had come from eliminated AIs had already been destroyed by the remaining AIs, the pirates wouldn't have had any resources to build Prototype ships anyway.

So, the question is:  Can pirates use strategic resources being mined by starbases that defect to them to build prototype ships?

This leads to another question:  If the answer is no, can this ability (or should this ability) be added to the game?
