Oh, I have.

You might have a few layers with a certain CMYK profile, and others with spot-colors (aka pre-mixed single color inks). That's a *very* common occurrence for business customers (logos, brochures, business cards, etc.)

Or you might have a spread that goes from one type of paper to another. Different media like paper type takes a different profile per paper.

A variant of that second case is cut-outs.
