I looked for instances of status and sstatus in the share code
and I think it would be easy to cut out the use of status and sstatus.

Well, not the same thing, but something related is the namespaces
package in share, which just exposes the Lisp package system to
the Maxima user. The namespaces global variable is a list of all
defined namespaces. If each share package were loaded into its
own namespace, then namespaces is a list of loaded packages.
Another idea is that if there were a Maxima "require" system, that
could obviate the need of the user to inspect the list of loaded
packages. e.g. user says require(foo); without needing to know
whether foo is already loaded.
