Yes, those are not part of the ABI.  I believe it's a mistake to
export them.

However if we do drop them, there are at least two tests that won't be
able to link (tests/mountable/test-internal-parse-mountable.c &
tests/regressions/rhbz914931.c).  Also all of the language bindings
use guestfs_internal_test_* (but not other guestfs_internal_*) in
order to implement the bindtests.

What is exported by the linker is controlled by: generator/c.ml
function: generate_linker_script ().
