There's many ships with a mountain of evidence yet remain a fanon ship (e.g. KyoSaya and sort of MakoHaru), having a larger amount of fan-based evidence does not make a ship canon, since- in the end, it is purely fan-interpretation and doesn't match up to what actually happens in canon.

I'll go back to my earlier message, where I quoted the definition of semi-canon.
 * Semi-Canon: One or both of the characters are attracted to or have feeling for each other. However, they cannot have formed a relationship. Must be 100% confirmed feelings in the work to be considered semi-canon. If you have to create an essay to point out feelings it is fanon.

The last sentence. I'm a Royai shipper myself and would love to see it become semi-canon/canon, but if you have to write a whole essay to "prove" your ship then it is fanon.

There's heavy implication that it's canon, yes, but no confirmation (a kiss, confession, one has a confirmed crush on the other, etc.). And without solid evidence of a romance the wiki cannot call it canon.
