That's mostly how it's working now. The only difference is that
the system path is introduced as the first item by the loading
system. Changing that would be interesting indeed, and trivial
of course.

The interesting point about that is being able to load just the single
command requested by the user. That's how it's being done in Smart
Package Manager: the file name *is* the command name, so when a
subcommand is requested, an import on that specific name is tried
by the command infrastructure.
