Exactly. Keep techs to the tech ruleset file. Easier to see what you are
doing and what you've forgotten.

Are you sure?

Looks like a design decision to me. I am not at all sure what will happen
if you allow such unreachable techs to be "existent" in the tech tree.

Not "maybe". You _must_ have such an option if you want to keep the trees
disjointed, which is a must for most modpacks.

But note how my patch is much more flexible: You can have forked tech
trees with a common base, where you can conquer/steal/give common techs
while special techs remain unavailable. No need for really anal options
like strict_tech.
