I think that it is an extremely important thing to consider how we look by default. Sure, we can have toggles for userbars and colors and formatting, but those new regular users won't dive into these settings - at least not immediately. We have to consider how our names look to the random people who come for ROM hacking. And if they get into the system, we might want them to donate. A community supporter status, new users might think, is a quick and easy way for them to get some desired respect and to feel part of the community.
I think that we by default should have a clear and obvious thing - which might be a userbar, might be something else - but it should show that we are supporters, and it should link to the donation page. To minimize confusion, and to keep receiving donations from people who want to support the community.
