Even without any feedback from the Linux kernel developers, I would be curious to hear What do other SCTP users say. So far I have a somewhat difficult time understanding that I would be the only one worried about ABI breakage? If that's the case, I guess it would be best to get the word out that people using Linux SCTP should better make sure to not use binary packages but always build on the system they run it on, to ensure kernel headers are identical. I don't mean this in any cynical way. The point is either the ABI is stable and people can move binaries between different OS/kernel versions, or they cannot. So far the general assumption on Linux is you can, but with SCTP you can not, so this needs to be clarified.
