I'm curious about which programs if you can share. I write few bash scripts which used to call sudo, and I replace sudo with doas in those. And in case of muscular memory I also added a bash alias so that if by mistake calling sudo in reality I'd be calling doas. So far no issues. O course I don't use fancy args, and what I really needed from sudo I used to include it in /etc/sudoers and now on /etc/doas.conf, and I believe I couldn't include a couple of options but they were not critical since I've lived without them so far. And it's weird to find actual software that requires sudo, perhaps proprietary software. One can actually live without sudo and without doas, as long as there's still su.

Not judging, rather curious, actually I've met several guys who write scripts which would benefit from using sudo/doas, but they claim better call the scripts through sudo/doas rather than adding them as dependencies.
