Yea expired card is what scares me the most, I think these days theoretically that shouldn’t be a problem because cc companies will proactively send out the new info to companies charging recurring payments (which can be good and bad).
If they really matter, extend registration for 10 years and keep adding one annually.
The bigger issue is that if your registrar sends a lot of spammy emails (ahem godaddy) you might miss the message reminding you to replace your expired cards.
