Except its already in the radios... so there is no 'cost' to make anything more expensive.
Not always. Some radios do have the ability built in. Some radios need an add on module.
I run a lot of Kenwood radios at work. Some of them require an add on Secure Cryptographic Module to do AES256.
And I've got some Harris gear, and that's an added feature, but the hardware is already in the radio.
Figure in export controls, so giving it away with all radios creates some challenges.
And then there's key management software/key loaders, etc.
