This is really helpful and, as you point out, a strange omission in the forum. Well done!
A brief suggestion: I wonder if you would save some hassle later on if early in the FAQ you distinguish between Aeroplan as a flight rewards program and Aeroplan Elite as a frequent flyer program (or whatever the appropriate terms would be). Many people are confused by the shared terminology.
Finally, in this sentence did you mean to use both “miles” and “points?” “Flights on most of these partners only earn Aeroplan miles (i.e. no SQx), and some only earn Aeroplan points on certain routes (e.g. Cathay Pacific).”
