"Variable length string identifier" is not defined anywhere, and the suggestion
to use "0x00" is also deeply unclear. I assumed it meant a nul-terminated
string!
Be explicit: you mean it must be a compact siz1\e unsigned int length, followed
by that many identifier bytes, followed by a compact size unsigned int subtype,
followed by optional keydata.

Since the sigOpCount calculation was copied from P2SH, and P2SH
restricts the use of CHECKMULTISIG with pushed integers the reference
implementation would not take into account the number of public keys for
17 to 20 keys (not representable with an OP_N) even for P2WSH.
Therefore it fallbacks to accounting for 20 sigops in this case, which
this sentence seemed to mismatch with.
Btcd and Libbitcoin use the same calculation as in Bitcoin Core.

This message, valid between version/verack for peers with version >= 70017,
would allow establishing at the time of connection that no transactions will be
announced/requested between those peers.
e549ed36e8 BIP155: change when sendaddrv2 is to be sent (Vasil Dimov)
Pull request description:
Mandate to send `sendaddrv2` to the peer before sending our `verack`
to them.
This way we know that the peer does not support `addrv2` if we did not
receive `sendaddrv2` from them before receiving their `verack`.

ACK e549ed36e8, I believe that the establishing of connection invariants in a such manner--in response to the `version` and prior to sending the `verack`--is the right way both for new `addrv2` message and for other future features.
