When did this 'officially' change? "SQL-MM defines the default SRID of all geometry constructors as 0. PostGIS uses a default SRID of -1."

Hello,
I see this note
"SQL-MM defines the default SRID of all geometry constructors as 0. PostGIS uses a default SRID of -1" on the PostGIS_Special_Functions_Index.html page all the way though 3.2
https://postgis.net/docs/manual-3.2/PostGIS_Special_Functions_Index.html
Since then it is not there.
I have not checked this question under versions < 3.4. AI results indicate that it was 3.0 when it started. A question from a user in our community indicates 2.0.
Perhaps it started at an earlier time and culminated at 3.3?
Thanks,
Michael
