Would you like to give me a new patch with the warning message pushed to
modify-* routines (as Stefan suggested).

This way a (message ...) can be issued as soon as any modifications -
add-or-replace or delete - happen on the buffer.  I think the extra
intelligence of checking for new value against the old value could be
dropped altogether. The message is merely meant as a warning, so being
paranoid and issuing a warning ALWAYS will also serve the purpose well.
