Much of this exchange boils down to this:
Rules imperatives are towards always focusing on the PD vs. Missiles rivalry. This is the true reason behind people being worried that armour is useless.

Side question:
Do you think an unofficial project aiming to either radically houserule G:SS, or make an SS-like system from scratch, that would be more general than the canonical G:SS, would be viable? At the very least, to make emulating different genres possible/easier?
