prerequiste override is ignoring techlevel

[Ollerus]

When a techtype has PrerequisiteOverride= code, even if you set its TechLevel to make it unbuildable (like 11), it could still be built once you have that override building.

I checked with the original game and the Ares documentation (see the first blue box on the big diagram on the Prerequisites topic), and they both concur that this is the expected behavior. If you don't want to override the TechLevel but still make the TechnoType buildable when the player owns a certain building, wouldn't an alternative Prerequisite.List work there?
