Hey, thanks to all who responded. I'm sticking with merely "bad idea", as it would also give the user block-level access to everyone's secret files. I know sudo already does this, but one has to manually clunk into that mode. Though there are still plenty of Raspberry Pi users who 'sudo ls', for some reason.

Wouldn't it be better to use SGID to enable access to disk devices only for the duration of that program's execution?
Author claims it's not possible. The program was written as a reaction to finding out that balenaEtcher (https://www.balena.io/etcher/) "phones home" with usage data. If true, this is unfortunate, because Etcher fixes all the fiddliness of using dd as root, it's truly cross platform, and avoids the Windows unzip bug. No-one's yet identified what exactly Etcher phones home yet, but that hasn't stopped the heat, light and fury of a Free Software Cause in the making … The new program's quite usable for now (even if you have to run it sudo) and appears to be cross-platform too. It's also a lot smaller than Etcher, which is an Electron app. Source repo is here: https://gitlab.com/bztsrc/usbimager
