[Richard Stallman]

Per doesn't want to implement this.  Is anyone else interested
in implementing it?

I don't see any idea, but a recognition of a well known problem. 

The problem is that custom-group property is not set for groups in not
yet loaded groups, but the custom-loads property is.  But the
custom-loads is also set for other symbols.  

The code choose to complete too much (with custom-loads) rather than
too little (with custom-group).  

It can be solved by storing the custom-group property together with
other autoload files.  Whether the cost outweight the benefit I don't
know.

customize-option and customize-face have similar problems.
