Changing this behaviour would not only apply to footnotes but to all
kramdown markup that is not correctly used. For example, a reference
style link `this is [some link][notdef]` that has no link definition is
currently just output as is (and a warning is added the no link
definition has been found). The same applies to footnotes without a
footnote definition.

So the current behaviour is intended and not accidental and as far as I
recall is what all markdown implementations do.
