Yes, it looks like it, but I'd rather go without an advice.  This feature 
isn't intended for my own customization, but rather for a package that I 
maintain (see [1]), and I am under the impression that advices in packages are 
really bad style.

Couldn't I just add my own menu to the 'local-map property of the mode line 
lighter text?
