Your justification is really no justification! "I am" is not a justification. Explain why you are interested in the version when you run a -s or -o. What question are you answering that you don't first locate by looking at the package name?
It's mostly when I'm wondering if the currently installed package is the latest version, but it also happens when I'm looking for alternative offerings of an already installed package. For example, I usually roll with the "dropbox" package from [archlinuxfr]; however, I sometimes like to check whether the AUR's offering is more up-to-date (which it currently is). Hence, I run "yaourt -Ss dropbox", which uses the output from 'pacman' for the repository entries. Is that the justification you were looking for? If so, can we get my "-{Q,S}i" patch included without further ado?
