I don't think this is the case. For one example, see the effort kib@
has been putting in (under Foundation sponsorship) on FreeBSD/i386.
One of my co-op students this term is working on building out our
hardware continuous integration testbed, including 32-bit Arm targets
like the BeagleBone Black.

Now, i386 has not been our primary reference platform for some time,
and I expect that for 32-bit ports FreeBSD will largely be cross-built
from amd64, arm64, or powerpc64 hosts. I think this is absolutely
fine, and we can still support 32-bit devices well, but our current
tier definitions don't fit this model well.
