Yea, I don't think that's good either. I'm all for evolving APIs when
necessary, but constantly breaking the same API release after release
seems indicative of needing to spend a bit more time on it in the first
round. I've a few extensions (one of them citus) that work across
versions, and the ifdef-ery is significant.
