But also only a comparatively few types of books are served by the extra features. A huge number of books are just simple text (where the font choice is as well left up to the reader) and images, and, while technically you can put a better quality pic in an ePub, on a 6 inch reader, it doesn't matter.
However, if the choice is converting one way or the other, yes it makes sense to use KF8, if available and if your reader supports it, over old mobi.
No reason not to.
