We had a three week trip to Italy last year and took it out. The much needed boot space was priority for us. I took the inflator kit from my GTA and a can of gunk/inflator as back up. We also had roadside assistance if the worst happened and I couldn't repair it.
Have also done the same, 5 times in the S4 spider, with no issues. The amount of space the full size wheel takes up in the well is well used for luggage.
The point is, what if I decided to take the GTA which doesn't have a spare, just the inflator? Does that mean I could never venture overseas in it? That would also apply to my Panda which also doesn't come with a spare - like lots of cars these days.
I guess you have to decide if you can wait for rescue should a split occur....
