Yes, that's right. I thought that there is not much value in testing
tests that are explicitly protocol v2 as another protocol, since there
was a reason in the first place why the test writer wanted to test it
with v2.

With the ability to set =0 to effectively disable the option (because
the minimum of 0 and 0/1/2 is 0/1/2), I thought it was less important.
