mekugi breakage came from a combination of things, primarily age and exposure to the elements, but even that would not be a severe cause for concern, as long as the tsuka core was tight. The bamboo mekugi was not intended to "hold the blade in" per se, but rather to keep it secured in a tight fit. It was positioned so that it would minimize the stresses of wobbling that would cause the tang to "dent" or compress the wood inside the core. Of course this would result in weakening the integrity of the handle, and if such a thing happened, the only security would be the mekugi. But even when bamboo breaks, it does not snap or shatter, it crush-fragments into fibrous strands that will stay in place reasonably well until another mekugi can be made. Another positive thing about it is that it is not very hard. Metal pins and various other hard materials are fit in only one direction as they're tapered, but with time, hard materials will "wear" the mekugi-ana (peg hole) in the tsuka, and can work its way loose. Bamboo has give to it and does not push on the wood in the same way.
There are lots of advantages to the use of properly cured bamboo for mekugi, not to mention plenty of advantages for traditional design and materials for most parts of the sword. But I'm biased
