Should we warn/log this error?

Maybe in some developer log but to the user, this error should make no difference at all. This convention/tag schema is mostly for our consumption at the end of it.

Can we add a comment that this logic is intended to capture assertions that CBMC generates for functions with missing definitions?
One way to check whether this logic matches other checks is to run the regressions without the --generate-function-body-options assert-false-assume-false that we pass to goto-instrument (which would disable the undefined function checks) and see if any other checks are captured by this logic.

After running the suggested experiment, no unexpected tests were found to change their result so we can safely assume that this logic doesn't capture false positives.
