AFAIK, "command" was a POSIX invention in the first place, so was a feature whose addition was legislated by POSIX. "command -v" was meant to paliate the need for an equivalent to the (broken / csh-only) "which" command. Since then, "which" has evolved to a command that does the equivalent of yash's "command -ve" or ksh's "whence -p", so it would make sense to add that. Not to mention that some people have objected in that recent discussion about the "exec" special builtin to "env" being guaranteed to execute external commands any longer, so we need an alternative like yash's "command -e".
