Oh, right. No.

However, now that I added the kunit_resource_destroy, I thought it
might be good to free the string_stream after I use it in each call to
kunit_assert->format(...) in which case I will be using this logic.

So I think the right thing to do is to expose string_stream_destroy so
kunit_do_assert can clean up when it's done, and then demote
string_stream_clear to static. Sound good?
