Not quite. Storable suffers completely different inconveniences from YAML. Storable can get tripped up if the levels of Storable on client and server aren't compatable. You have to be a bit careful if the endianness of the client and server are different (I think there's an "nstore" and "nthaw" for network-order storing) - assuming the levels of Storable are otherwise compatable.
But it is part of the core, so it's already installed. That inconvenience is unique to YAML. (Well, unique in the context of YAML vs Storable.)
