Yeah it's a fine line. I 100% play it out in the regular season even if my team's out, that just feels fair, for the reason you say. For consolation, less so, but I also make a point not to drop anyone too valuable that might influence the real bracket. Fine line.
I do still mostly try to set my lineup "for real" in consolation, though. But I can't always be bothered, when busy (or when managing other teams still alive) to check on those last minute game-time things, which is how I've ended up with some late inactives the last couple of weeks.
