After a bit more experiments, I tend to agree with you (especially given the huge number of symbols exported by libzpool!). Attached is a patch that simply emulates upstreams "break with every release" (tested with sid and stretch-backport builds). I prefer this approach to hard-coding the exact versions in d/control, as it also works for other packages linking with ZFS libraries using the shlibs mechanism. I think I will start a discussion with upstream regarding their plans for future ABI guarantees and proper exporting and versioning of public library symbols. Switching to proper symbols based versioned dependencies in Debian should be possible without much pain anyway, if and when upstream decides to declare the library interface (somewhat) stable.
