Comment (by davidsarah):

 BTW, if you drop the feature of being able to derive a verify cap from a
 read cap off-line, then a verify cap could include the information
 normally stored on the server that allows to verify a plaintext off-line
 without doing erasure coding, and read caps could still be optimally
 short. However, in practice I think off-line derivation of verify caps is
 the more useful feature.
