Following up on this. I sent an email out to the team and got a response already.
To summarize, they would rather the solution work through updates for security fixes, but they were willing to compromise if automatic updates were disabled with the option for users to manually update somehow:

Yeah, one of the main points of this project is to help them reform Sec 1201 of the DMCA.
As far as for how to do it, I’m not sure if you would have to come up with something that would work even through an official Samsung update. From what I can tell, it would be enough to have it work with Home Assistant instead while blocking future updates. It’s definitely worth a question to the bounty team to get clarification on that point though.
