This would be an incredibly useful feature, I think. It was part of the motivation for our sandbox, honestly. It should mostly operate as a pass through the the various package managers - but with some extra security checks.
In this way a `phylum npm install <pkgName>` would perform the typosquat checks _and_ limit access to system resources. You can even alias this as `alias npm="phylum npm"` so that it's easier for the user.
