Over a two or three week period this oxygen *could* cause a problem. Same with airborne microbes. Not saying these *will* cause problems, but to feel more secure some brewers eliminate the possibility by minimizing head space.
Sanitizing well and leaving it alone seems easier to me than moving to minimize headspace. I don't keg or have CO2 on hand though.

I forgot to mention one other reason some brewers rack to a secondary, and that is to get the beer off the cold break trub and yeast cake. Traditional German brewers often remove it for flavor reasons. The desirability of this has been debated for decades though.

For me the reason I use a secondary fermenter is that for stronger beers I like to age them quite a while and I prefer to do that in a carboy rather than let them sit in a primary fermenter on the initial spent yeast for 3 to 6 months.
