Support response time is part of accessibility, not just documentation.

Clear documentation gets someone most of the way there.

What happens when documentation isn't enough and they need to ask a question matters just as much as whether a platform is genuinely accessible.

A slow or unclear support process can undo the work of otherwise excellent docs, especially for someone new who doesn't yet know how to work around a gap on their own.

Accessibility isn't just what's written down. It's what happens when the written-down version isn't quite enough.
