Looking in another place, https://www.freebsd.org/platforms/ , indicates:

14.x for 32-bit ARMv6 (armv6) has Support Tier: Tier 3

https://docs.freebsd.org/en/articles/committers-guide/#archs reports
for Tier 3:

QUOTE
Tier 3 platforms have at least partial FreeBSD support. They are not supported by the security officer, release engineering, and Ports Management Team.
. . .
The FreeBSD Project provides no guarantees to consumers of Tier 3 platforms and is not committed to maintaining resources to support development. Tier 3 platforms may not always be buildable, nor are any kernel or userland ABIs considered stable.
END QUOTE

The projected 15.x Support Tier is listed as: Unsupported
