A small whisper from the sidelines among you professionals...
What about the need to recalculate the landing distance required from where you eventually get the wheels down after reacting to a 30Kt gust up the chuff over the threshold, especially when the ground speed is now going to be faster by 2X the gust speed (ie 60 Kts faster) than it would have been landing the other way.
Was this a serious question? Are there any circumstances in which a commercial aircraft in normal operations would accept a runway with a gusting tailwind? "Gusting" implies - to me - more than a few knots. Is there a definition, if the gust speed is not provided?
