S 3.2.1.

```
Each side MUST initiate a single control stream at the beginning of the
connection and send its SETTINGS frame as the first frame on this stream.  If
the first frame of the control stream is any other frame type, this MUST be
treated as a connection error of type HTTP_MISSING_SETTINGS. Only one control
stream per peer is permitted; receipt of a second stream which claims to be a
control stream MUST be treated as a connection error of type
HTTP_WRONG_STREAM_COUNT.  If the control stream is closed at any point, this
MUST be treated as a connection error of type HTTP_CLOSED_CRITICAL_STREAM.
```

Rather than having this rule, wouldn't it be easier to just require
a specific stream number for this stream? Then it would not be possible to have >1.
