"No" to what ? My Q above was in regards to the omitted http_access

The 'type-1' I am speaking of is the initial NTLM credentials token. Not
the version number. All LanManager based exchanges (LM 1.0, LM4, LM
32-bit, SMB LM, NTLMv1 NTLMv2, NTLMv2 extended) begin with a type-1 token.

Yes, that is worth testing for.
