We try to avoid anything to do with SGMII and 2500 because it is
technically wrong. Cisco never defined SGMII for 2500, it is something
silicon vendors have made up, without any foundation in any
standardisation. We much prefer to refer to it as 2500BaseX with
broken signalling, which is a much more accurate description.
The TRM is also not a public document. If it was, i could see some
value in keeping with the naming, but since ~0 developers have the
document, this is less useful.
