Okay, now you're just saying absurd extremes which are only polar opposites of the extremes the other two are saying. Calling Samus a female might have been a spoiler in 1989, but has not been a spoiler since Return of Samus since the game is really upfront about Samus's identity in each and every single game.
This isn't like we need spoiler tags for the Bible or anything, but the notion is that time and place matters. In a FF Community thread, the poster who has not been spoiled is assuming the risk by going into a topic filled with decade+ long-time fans. In a topic like this, where it is not really an OT but more of an informational thread on the mechanics of the Steam release itself, spoiler markings might not be a bad idea until the OP or a mod gives leeway.
