Not everything that is RGB is bad in today's print publishing. While we certainly don't want to use sRGB images if we can avoid it, there are some good options for color spaces in media-neutral design workflows (e.g. eciRGB, Adobe RGB).
Being warned that certain undesirable color profiles are being used in linked images, and skipping those that are considered okay, should improve any modern desktop publishing workflow.
A "missing/no profile" option should also be included, as these cases completely defeat the purpose of color management workflows.
