Yes, you seem to want to keep this debate alive.

You don't seem to understand the pain it causes downstream.

The projects in question have been nagged, but that doesn't solve the
issue. It did cause the libosmium & osm2pgsql authors to drop support
for GEOS. It did not convince the OSSIM developers to switch to the C API.
Not accepting such software for packaging is a disservice to our users
and hence undesirable. Packages are part of a larger ecosystem which is
affected by removals down the tree, e.g. the removal of OSSIM causes the
removal of OTB.

It is however a problem that slows adoption of newer GEOS releases, and
by extension newer PostGIS releases when they depend on features in

Why do you care so much about the C++ API? What keeps you from using the
