Perhaps Canon and the vast majority of photographers don't share the obsession with this non-issue?

Perhaps Canon and the vast majority of users are ignorant of the fact that having no extra noise added by the camera after the photosite read could allow tremendous highlight headroom at higher exposure indices, with smaller RAW files. Even with Canon's measly 1-stop HTP, it gets risky at base ISO, especially in non-ideal light coloring, and with arithmetically pushed 1/3-stop ISOs.

With high enough DR at base ISO, a camera doesn't even need higher ISO gains - they serve no purpose, but to make bloated RAW files with discarded sensor highlights.
