It's not that we shouldn't provide it, but it doesn't make sense invest into when OpenBSDs security is so far behind the rest of the industry. A program being able to steal your .ssh keys without you knows is unacceptable. Not only that but programs can keylog you, take pictures of what you are doing, or take remote control of your computer.
I doubt you could keylog my openbsd server that I remote into over ssh or serial.
I also doubt you can take pictures of me when it doesn't have cameras attached. If it did and you were to take pictures, you'd see some blinking leds and cables all day.
And I highly doubt you could take remote control even if I had openssh open to the public.
Perhaps your industry just doesn't care about the same things the openbsd community does.
Edit: I missed the ssh key stealing. My keys are always encrypted.
It would be very powerful to get malware into ports and packages. It would also be noticed rather quickly. OpenBSD developers tend to run everything through dynamic tracers and other debugging tools.
