I understand that and hence I propose to create an additional object
type which allows me reference a command indirectly through its ID (one
would only use it when the Command-Object is not directly available).

In my proposal the framework code would not be affected by the way
because one simply always calls getCommand() and the resolution happens
within the Method.
