Granted. That's the maintainance cost that some are trying to avoid :)

Uhm, isn't this in contraddiction with the problem expressed above
of not knowing which of the 20.000+ packages need a rebuild ?

Where can I find this NEEDED section ? Can't see it with apt-cache show
nor at https://packages.debian.org/jessie/postgresql-9.4-postgis-2.1

Btw, you meant that postgis module 2.1.6 has "liblwgeom-2.1.6.so"
in its NEEDED section ?
