Well, the terminology is Adobe's, not mine, but I actually think it is the best default for a typical CMYK workflow. Most printers want final CMYK, and will ignore profiles anyway. Generally, I want to avoid layout programs from deciding to change my CMYK without my specific consent, while at the same time, leaving less chance of an unwanted conversion happening downstream. So I will rarely send anything but PDFs, which I find most vendors that I (or, more accurately, my clients) deal with (all major players in the printing industry) specifically request to have profiles removed.
The default can easily be overridden for specific images that are imported by using the Show Import Options of the selected image, and changing the profile from Use Document Profile to the correct source profile. The image will then be separated at output.

If the linked image has an embedded profile that describes its color appearance accurately, and that embedded profile is different from the active profile (default or assigned) in InDesign for that color mode (CMYK or RGB), then, by stripping the embedded profile, in effect you are altering the correct appearance of the linked image by assigning to it a different profile than the one it was intended to work with, right?

But that would be a coincidence, and I think you will agree when I say that accurate color should never be left up to coincidence or guessing.
