As the standard kernel versions are set up (no source changes)
they support:

# sysctl -d kern.supported_archs
kern.supported_archs: Supported architectures for binaries

# sysctl kern.supported_archs
kern.supported_archs: aarch64 armv7

It is possible to modify the kernel source a little and build a
kernel that will list armv6 instead of armv7. But that does not
imply that allowing "aarch64 armv7 armv6" all at once would be
that simple.

FreeBSD servers are not normally rebooted into tailored kernels
for specific types of builder activity, especially not into
kernels that require source code changes to build the
alternative kernel.

FYI: It is proposed to:

A) stop all package building for armv6 for all branches (soon)
B) have armv6 be tier 3 (soon)
C) stop building armv6 main [so: 14+] snapshots (soon)
D) do not create stable/14+ releases or artifacts ever
E) remove the armv6 specific source before stable/15
   (but after stable/14 is created)
