I said in a later reply that I thought format was more for human
readable formatted output, and if this is the case (that's a big
`if'), then the change doesn't make sense to me.

set-text-properties is perfectly fine.  I was bothered by the
incompatible change and the fact that all my users that upgrade to
21.1 will see their emacs-lisp interface broken.  The method of the
fix doesn't bother me at all.
