Why would you want such a large pad? 
For most users and most gamers they would consider this pad a deskpad. Similar to what lawyers and bankers have on their desk with those leather style deskpad. They would mostly consider it to be a fancy cushion for their hands, arms, and wrists.
For some gamers though, which there is a demand for ever larger mouse pads. This mousepad falls on the category of either quite comfortable for their sensitivity or great for lowering their sensitivity even further and testing out even lower sensitivity. In other words they can take the entire mousepad and slice it up into their given sensitivity ex: they use 30cm/360 and they have in total 3, 360 degree turns a 1080. Or they just lower their sensitivity even further maybe even the whole size which would be about 90cm/360.
But as I said in the first page of this thread. Just because the ripper pad is so big doesn't mean anything if the gamer who has it doesn't like the surface of it. Plus it's thin not all gamers like thin pads, some might want a little more backing for the surface.
Aside from that the only issue I would see is if the person didn't have a big enough table then they couldn't really use the mousepad to it's full length. In a way your right it is kinda awkward to use such a long mousepad. Some might say either raise your sensitivity or learn to lift off your mouse move it to the start of the mousepad and sweep again to complete the turn as fast as possible.
