FreeBSD 15, 16 to end support for 32 bit platforms
FreeBSD is deprecating 32-bit platforms over the next couple of major releases. We anticipate FreeBSD 15.0 will not include the armv6, i386, and powerpc platforms, and FreeBSD 16.0 will not include armv7. Support for executing 32-bit binaries on 64-bit kernels will be retained through at least the lifetime of the stable/16 branch if not longer. (There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.)

I don't think this is too egregious of a timeline, but there's always someone with some weird edge case that gets bit hard by deprecations like these.
