The NEWS file doesn't necessarily describe only stuff documented
somewhere, it also describes changes that aren't documented anywhere
but the source code.  Suppose someone read the source of replace.el,
found out about this property, and uses it to do something, either
privately or for some 3rd-part package.  Put yourself in the shows of
that person and ask yourself whether you'd like to know that this kind
of change has been installed in Emacs.

Since you introduced the new format, you probably thought it to be
better than the existing one, right?  Then telling others about that
would be a good service, IMO.
