It took me about two minutes to find out which implementations do
advertise that feature without supporting dialback errors:
prosody (.im)
tigase (.org)
m-link 14.6a6 (jabber.org, certainly does the right thing [tm])
jabberd2 (xiaoka.com)

This is not advertised by and ejabberd, openfire or jabberd1.
Advertised (with errors) by m-link (15.x) and psyced.

Let's just bump the version number of the stream - after all this is 
about not sending a stream error in response to a dialback request.
