So a test case that doesn't use a novel CC is "simpler" in that sense, to me at least. (it's not a guarantee, it's possible the bug is only reproducible with the default CC, but more often than not that's not going to be the case, I think?)

This is a very x86 centric view. I might go so far as to consider CCC to be the most complex of the calling conventions, others add restrictions
