We deploy larger networks with our router silicon and we _use_ IPv6 extension header to transport signaling information. Period. Our need is not on the protocol side - UDP is fine for all - we need additional extension header (think about roaming information). And we _have_ actual problems with the current situation! This is why I wrote the I-D back in 2011[1]. I remember a time where ECN did not work properly and where dropped occasionally by broken middleboxes. LKML started to enabled ECN and things improved over time. We should not stop solutions here because administrators/vendors infringe protocol best practices. We should focus on an proper protocol design which enables possibilities. Hagen [1] http://tools.ietf.org/html/draft-pfeifer-6man-exthdr-res-01
