I'm considering having multiple research projects for a given alien weapon.
One project as a quick "How do I make the unfriendly end of this thing work?" project, followed later by a more demanding "How does this thing work and how do I build more of it?" project.
I would like to unlock one UFOPedia page upon initial research, then remove that page and replace it with another upon completion of the second project.
Can I ask for something like a "removedby" field, which will basically act as the inverse of "requires"?
Hrm. This might not be viable if "id" must match the actual item ID, and must be unique.
