You can try to twist my words in any way that pleases you.  However, the
fact is that people who put forward a heroic effort in modernizing NetBSD
will not be held accountable for making sure prehistoric architectures
keep up (*).  Some of our older ports have active supporters who keep
the port up to speed with MI changes, set up emulator support, publish
test run results etc.  These ports will continue to be supported by
NetBSD indefinitely.

*) just to be explicit: prehistoric != non-x86
