Somehow I missed the existence of that command, it would've made something I did the other day a lot faster and easier.

Anyhow, from being in groups with people who do scan multiple directions at once, it appears that most of them use aliases rather than 'scan all'. In light of 'scan all', I don't know why they use aliases, but that's what appears to be going on. Scan all can have a use at times, but adding extra info to the scan still doesn't seem useful to me.
