FWIW, I did exactly that on my OpenBSD machines when doas was first introduced and I can't think of any issues I've encountered.

Maybe? The one that sticks out in my memory is running sshuttle on Arch Linux; Arch considers sudo to be part of the base group, so it doesn't want to remove the package, and I think sshuttle invokes /usr/bin/sudo with special options to control it. But... I might try just making a sudo symlink in my path and see how it behaves; thanks for the idea:)
