I'm sure it is, but it's not a huge install base. The primary focus of FreeBSD is i386/amd64, there are only a small number of other architectures supported and they're all Tier 2 or Tier 3. ARM and ARM64 is still Tier 2 but there's work being done to get this to a Tier 1 status. As there's only a small number of developers working on any of the Tier 2/3 architectures I very much doubt there's enough "spare" time to add another architecture. I mean, who's going to support and maintain it? You?
