Ok, I'll try to explain in more verbose terms how I see this.
Not all selftests use the harness and I'm not yet confident that SGX has
to. Unfortunately, ugly is for me something that I cannot put metrics
on. Also, often "ugly" is actually better than layering because it is
more transparent.
The test is comprised of simple POSIX calls that everyone knows whereas
using kselftest harness requires learning new framework. Less macros
makes code also easier to debug and pair compare to dissembly when
required. I've done the latter at least a few times.
It will also add a requirement for code reviewers who are simply looking
for a code example how SGX works also to learn the harness. In the scope
of the patch set the selftest serves as a such example.
