It never occurred to me to judge a flashing tool based on its internal architecture and language/framework choice.

I judge it based on whether I get a bootable bit of flash out the other side.

Rufus has made multiple unbootable drives in the years that I've used it. Etcher has yet to made one and I used to flash drives constantly - multiple daily - until I switched to Ventoy which is the way forward now.

Besides that, every single of maybe a few dozen times i tried it, it said checksum error after verification. On different systems, with different media. Interestingly there were no errors in reality. I dismissed it as a well meaning toy for dummies. Or maybe data gathering spyware.

Thouroughly unimpressed with it and any project recommending or even insisting on using it.
