It's not a faux pas, it's your personal preference. I RP my char as having done everything (or some similar variant of everything) up to Coil, too, since that's what's actually taken place and has been accomplished ingame. If it comes up in conversation, sensible folk will say "I wasn't aware of that! Now I know!" then move on to the next topic. Even "You're lying! That can't be true!" is still an IC response that can be expected. It just means they're playing a poorly informed, ignorant character in denial.
But if it comes up in conversation, and someone detonates in an OOC snit over it, that's what the blacklist is for.
The only thing you need to do, really, is watch the semantics. "I was in A team that helped destroy the Praetorium" is generally preferable over "I was in THE ONLY TEAM that destroyed the Praetorium," since it gives others more room to go "Oh I was in another Operation Archon team there too!" Same goes for primal battles. Square Enix has actually provided an ongoing threat and plot device with the constantly regenerating/resummoned primals, so anyone can plausibly say, "Ifrit's back gotta go spank him again" "But I just spanked him last week! D:"
