Evidence #2:
Token suffix is well established
➤ "Suffixes such as, but not limited to: “Token”, “Coin” should generally be avoided, unless a name with suffix is already well established."
The token suffix is well established, as I have already proven. All relevant aggregators use "Synthetix Network Token", therefore the token suffix is very well established. And not only big coin trackers use that name, also official sources use "Synthetix Network Token", because that's the name of the SNX asset.
➤ "The name should be the most commonly used name to refer to the asset."
