Which isn’t really fair, since we’ve done everything necessary to make things easy: the ABI never changes, there’s never a reason to not just dump the latest GEOS into place. What can we do to convince packagers we are sincere?<br>

A recent case is someone showing on PostGIS IRC asking why ST_Subdivide won't work as expected in their 2.4.latest and the issue was they used unpatched GEOS.<br>
