I personally think some people have side-effects pre-invasion but thought it was normal or wasn't at all brought into the spot light like Kikuchihara who thought that his hearing was just unnaturally sharp until it was classified as a C-type side-effect. There's probably a lot of non-Border people who has side-effects but considering that Border is stationed in one city only, and that probably some of them didn't like to be in the front-lines, it's only natural that they didn't become an Agent.

It's kind of a good twist actually, to explain that superhuman abilities are from trions, even the ones that are not related to Border, since everyone has trion organs.
