If it did, we could just turn off gdb and life would be good…

Please see https://wiki.freebsd.org/GdbRetirement and edit it based on testing that you can do. That wiki page is there to drive this issue to Dimitry’s answer in the fullness of time.

If we had kgdb support in ports and arm worked, we might be able to get away with it, but we’re not even close on either of those at the moment...

P.S. Minor quibble: it does work on powerpc, but not sparc64. Doesn’t change your point though.
