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.
