There are other modes like CFB, CTR, OFB, and IGE. While they may not be as popular as CBC, if we want to support them at all (e.g., if a particular piece of hardware like the VIA Pardlock supports it), then we need to generalise the block ciphers. If we continue to do it as we do now, we'd end up with a huge list of functions in cipher_alg.
