Basic storage-developer conservatism. Zero was the behavior before read-hash-mode was implemented. As strongly as some of us might believe that such tweaks lead to better behavior - as I did with this one in 2012[1] - we've kind of learned the hard way that existing users often disagree with our estimations. Thus, new behavior is often kept as a "special" for particular known environments or use cases, and the default is left unchanged until there's clear feedback indicating it should be otherwise.
