>From [the spec](https://tools.ietf.org/html/draft-ietf-quic-http-15#section-4.2.6.1):

```
   SETTINGS_NUM_PLACEHOLDERS (0x3):  This value SHOULD be non-zero.  The
      default value is 16.

   SETTINGS_MAX_HEADER_LIST_SIZE (0x6):  The default value is unlimited.
```

It seems inconsistent to reuse 0x3 while forbidding other setting IDs from RFC 7540.  `SETTINGS_NUM_PLACEHOLDERS` is not the same as `SETTINGS_MAX_CONCURRENT_STREAMS`.
