Well that's the tragedy of not contributing back upstream then.
If there were companies actively maintaining the 32 bit port, there would be no plans of dropping it.
32-bit x86 CPUs haven't been made in years, companies building products based on FreeBSD switched to 64-bit x86 or to other architectures long ago. It's not that work on i386 is being done but kept in private repos and not upstreamed -- work on i386 just isn't being done at all.
The companies use what their supply chain has, which ends up being 64-bit by default. They're not building their own 32-bit CPUs.
