[gdal-dev] What is the status of KML?

We have historically provided KML support in our GDAL-based import system using an old version of libkml which dates from the Google Code days. We had a cache of the .zip file so have not needed to download it afresh for a long time. I am belatedly testing using the v1.3.0 version available from https://github.com/libkml/libkml which was somebody's attempt to keep that library alive, but it is nearly as ancient (2015).

However, while naive replacement of our previous autogen-based libkml build (both shared and static) with the newer CMake-based one compiles just fine, GDAL (currently 3.10.3) is not at all happy with it as a static build, although a shared build seems OK.

Does anyone please have a known-working build incantation for libkml 1.3.0 plus current GDAL for an all-static build.

Alternatively, Even or whoever, is KML still a thing? How many people are likely to care if we deprecate support for it?
