Comment (by robe):

 @pramsey so how do you feel about dropping it in PostGIS 3.4.1, or should
 we just push that can down the road?  Doing version audits sounds like it
 would take a bit more care and testing.

 I'd like to release 3.4.1 soon like this weekend, and trying to shove this
 in quickly feels a little wrong, so I'd rather just make this a 3.5.0
 thing, or maybe a 3.4.2 thing where we can spend more time on 3.4.2
 deciding how to do the version checking or if we even care to.
