I'm not being evasive. My answer stands. You get to decide how you portray your character and not a single player at my table, nor me as DM, will ever question it.
Your inability to answer a very simple and direct question absolutely reads as evasiveness, so you may want to be aware that argument-wise, you look like a politician squirming to avoid directly answering a question in an interview. I'm sure that's not how it looks to you but hopefully it's helpful to understand how it may appear from another perspective.
So we have to go with inference, and thus we must see the answer as "Yes". I guess that's fine, but I'm super-skeptical that's how it actually works out at your table.
It's totally fair to call your interpretation bizarre or legalistic though, I'd suggest, and I don't believe for a second it's intended. It could be shattered in a heartbeat by a new 5.5 PHB even slightly differently describing what stats are. I guess it very much fits the title of the thread, so there's that!

Another way of thinking about it might be that they leave it to the individual groups and players to decide. In my games, if you don't want to use "OOC knowledge" you can just choose not to do that. What you don't get to choose is how someone else at the table handles it since that is their character. This seems to me to be the easiest solution.
I think it's fair to complain to the DM if one player insists on using OOC knowledge and ignoring their stats if the rest of the players, by unspoken agreement and long tradition (like, 40 years of tradition) are not using OOC knowledge and treating their stats as meaning something. It's certainly fine for a DM to tell a player to get wrecked for trying to use OOC knowledge (which would include some of the proposed approaches to stats).
