Your choice and I don't fault you necessarily - just don't feel you absolutely have to go - it's just a large high end lounge. FCL B has the same stuff, shorter walk typically. Me? If doing non-Schengen to non-Schengen like you, I'd probably lounge hop as much as possible in the terminals.
Not that passport control is arduous but I'm only making the trek to the FCT if I have 8+ hours to kill - and this is because I would first be going into the city, or Mainz, and then returning to the FCT. Otherwise I'm schlepping to the nearest FCL and camping there.
Off topic, so I'll get back on topic: Awesome itinerary!
