It's not that hard to understand relays with some decent exposure. Jumble is gaining popularity for good reason. The concept is only made harder to understand by trying to frame them as some boring but necessary, and probably cumbersome, settings.
Just because they're necessary doesn't mean they need to be a burden. It can be the opposite. I can attest to that, and I feel like I need to because I'm probably a decent example of the learning that can happen. I still don't know how to make my laptop stop losing its wifi connection when it falls asleep, but I can explain what relays a person might want to consider for publishing to attain their desired experience.
