Comment (by robe):

 I think for PostGIS 3.5.0 we can dispense with the pgaudit version check.
 I figure 9 months from now is far enough that people should have made the
 switch in pgaudit already.

 As to for PostGIS 3.4.1 2022 is not that long ago that I wouldn't be a
 little worried.  That said  pramsey you have a sense of percentage of
 people that would be impacted if we remove this from PostGIS 3.4?  I
 wouldn't bother with PostGIS 3.3 since there is a much higher chance a
 person installing PostGIS 3.3 is running with an older pgaudit
