Hmm.. Then a slightly different question: Do you handle OBS4 transits differently then? I have a few places that I go that actively block Tor - OBS4 and Scramblesuit both traverse these blocks.
Because of that, I primarily run those transits, and I tend to get captcha hell still. I'd be willing to debug on my end.
I think you're misunderstanding things, Cloudflare has no way to know which pluggable transport (such as obfs4 and the retired scramblesuit) you use to access the Tor network. They're only interested in exit traffic.
