Hmm, but doesn't it let you complete any ships in progress? At Armor TL 4+, you could surely come up with an interim design that doesn't involve stealth armor, if you need to start new warships while you research Stealth Armor or Fighter Carriers. Since you will have the other prerequisites already, it won't take all that long to get the new tech area.

But ya, it's imperfect for old games upgrading. If people are unconvinced by my above suggestion and interested in a variant patch, I could make a 2.4.3 that has the other changes but not the new tech areas.
