In practice, the files can be viewed just fine in any standard-compliant viewer without any awareness of custom tags.

Agree! Also some applications have "special" features that rely on data stored in private tags which, of course, you don't have any idea how to use.
Also, the difficulty in my experience is the getting data back in part; getting data out is usually a lot easier (you don't need to care about those tags).
