According to Section 4.2 RFC 4253 (https://tools.ietf.org/html/rfc4253#section-4.2 ), “Implementers who wish to maintain compatibility with older, undocumented versions of this protocol may want to process the identification string without expecting the presence of the carriage return character for reasons described in Section 5 of this document.”\
Currently, Twisted Conch does not implement this feature.

Research direction
Start by reading RFC 4253 Section 4.2 and the related Section 5 discussion, then trace Twisted Conch's SSH identification-string handling. Verify how the current implementation treats input without a carriage return and define tests that demonstrate compatibility with that form. Done means the behavior supports the RFC-described legacy identification string without breaking standard processing.
