At time of writing (early 2026) the minimum supported version of GEOS is
3.8. There are a number of functions that GEOS has deprecated support for,
see a full list at:

https://libgeos.org/doxygen/deprecated.html

An audit should be conducted of used functions against this list and then
migrate away from them.

Two functions that have been noticed so far are `initGEOS_r`

link] and `finishGEOS_r`
