But what is a "public header"? In this case, you're talking about a
header file that's part of a library that is an internal
implementation detail for zfs(1M) and zpool(1M) and so on.
It was likely a mistake to ship that header, or a compilation symlink
("libzfs.so"), for something which is really not meant to be used from
outside the consolidation. If we do anything on that front, it should
probably be to stop shipping them to avoid future confusion.

We've already effectively done this with "libzfs_core". It has a
different SONAME by virtue of being a different library entirely: one
with a public, stable interface which won't change over time. Within
that public library (as with other public libraries) we take
compatibility very seriously, and won't break third parties with
changes.
Cheers.
