3. there always is this tiny chance that the GA tells us to keep the cert

I've never liked the idea that SEs can sponsor Es with E certs at SE window. It defeats the purpose of the 7 days window in a way. Perhaps it's my solo travel style that influences my concerns as I'm sure I would have a different opinion if I had an E SO who would travel with me often.
