I have been thinking more about this problem recently.

One idea is KISS: just load all the commands and functions at startup.
I avoided this initially out of fear that it would be too slow -- but I
never measured it.  Maybe it isn't so bad.

A second idea is to install the Command objects eagerly, but have the
implementation lazily load the actual code.  That is, there would be a
single Command subclass that would take a help string, a module name,
and a class name (string) arguments, and then when the user invoked the
command it would import the module and instantiate an object to which
the command operations would be delegated.

This approach would work for convenience functions, too.  It is also
easy for 3rd party users to use.

Also, we can always start with KISS and move to the lazier approach if
it turns out to be too slow.
