Question on Licensed Frequencies and Tower-Sites

[Tankseb]

Often I'll go on something like maprad.io and I'll look up a specific site to find details on frequencies and control channels. I'll often find tons of frequencies in the 800's that aren't on the RadioReference Wiki.
An example would be the Royal-Road site in Fredericton. On RR there is only about 4 actual frequencies listed for the site, but when on the official licensing there's a lot more.
Would anyone be able to explain why these aren't listed? Here's a photo of the Radio Reference Wiki;


In comparison to the actual licensing;

These would mostly be input frequencies for the tower sites, vehicle repeaters and could also be for simplex if the radio(s) are programmed for it. Someone with a more in-depth background can likely provide a better explanation.

why these aren't listed

They are not needed for scanner listening. They represent the entirety of the license IC has issued in the trunking world. They serve no real purpose to listen to. In a conventional system (repeater) there is a benefit for me to listen to the input, for a scanner, not so much,
