pkgsrc is in a similar position to Debian, although less well baked,
with proj6 in wip (sort of like Debian unstable, but not really), and
having to define ACCEPT_USE_OF_DEPRECATED_PROJ_API_H to keep some things
building.

I don't want to have multiple proj versions in pkgsrc,a nd I don't want
to prclude libosmium, libspatialite, mapnik.

I feel that the "rip the bandaid off" notion is counterproductive, as it
really means "break things for users so that packagers have to decide
between old proj and dropping dependencies".

The real question is whether removing it would be a real gain, or just a
club to get people to update.  Certainly it's going to happen, but I
think it would be good to let the dust settle on proj6 first.  It feels
like we as a larger osgeo community are making progress on that and in 6
months or so I'd expect the situation is much better.
