Are you seriously going to argue against improving accuracy of the measurements? Would you say the same about the speed of light? Is it only 299792.458 km/s "this week"?
Bad analogy. That is the speed of light by definition, not by measurement. The second is a measured quantity. The metre is defined as the distance light travels in 1/299792458th of a second.
