Remove Rate-limiting and quotas (Appendix A) when finalizing the document.

[mnot]

What's the purpose of this section?

[ioggstream]

This section contains parts of the original introduction to explain that:

• we are not inventing a new way of conveying ratelimit information;
• we aim at standardizing the behavior around a well-established practice.

We moved it in an appendix when the spec started to be implemented.

[mnot]

Is it going to be removed when the spec is published? I don't think it adds much for readers.

[ioggstream]

If @unleashed agrees, when we finalize the spec we can remove it together with the FAQ section.

[unleashed]

Perhaps the appendix itself could've been part of the FAQ to add context. Agree on removing both.
