It looks like you can't in general distinguish between two ways of using
the service:

- A command (gdu) is an instance of a basic command (du) for which
completion exists, but under a different name (as above).  The basic
command might exist but your best bet for picking the right version
is to run the new instance.

- A command has some behaviour related to, or acts as a front end for, a
basic command but possibly doesn't fully implement it and might not be
useful for finding out the version of the interface.  Then you'd need to
run the basic command.

In the first case you have the simple alternative of defining

#compdef gdu
_du "$@"

which fixes the service for you.
