Original:

HTTP/3 frames

HTTP/3 means setting up QUIC streams and sending over a set of frames to the
other end. There's but a small fixed number (eight!) of known frames in HTTP/3. 

I was reading https://tools.ietf.org/html/draft-ietf-quic-http-17 It list 9 frames:

1. DATA
2. HEADERS
3. PRIORITY
4. CANCEL_PUSH
5. SETTINGS
6. PUSH_PROMISE
7. GOAWAY
8. MAX_PUSH_ID
9. DUPLICATE_PUSH

So may be you can change the "eight" into "nine"? Alternatively, you can remove "eight" altogether, just in case if they add/remove any frames in future drafts.
