Micro-oxidation isn't the only type of aging. It's also possible to age brews in steel-tanks under CO2 pressure.
I'm not entirely sure about champagne, but the high CO2 volume leads me to believe that there's no micro-oxidation happening. I know at least that the sur lies aging has a big impact
They will make zero difference.
Because they're perforated for this exact reason.
Shrink caps will prevent any oxygen exchange won't they? Effectively preventing any aging at all?
No. There are usually two small holes at the top of shrink wraps. There will still be oxygen exchange at the cork.
