Is there a strong case against only using nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl as your signing devices? So far I can't see no downside. Supply chain attack = unlilely + nowbody knows you even have it. Anything I'am overlooking?

Everything has tradeoffs, but if you're comfortable verifying the authenticity of the software and know what safeguards make sense to protect your key(s), myself and many others see this as a very reasonable approach. With reproducible builds coming very soon, the assurances get even better.
I love your balances approach. It might not be for everyone but it is a very valuable tool in my toolbox and I thank you for bringing this idea to life.
Depends on how you trust any single device you rely on.
The tradeoffs of packaging & verifying yourself, or trusting a company to do it all for you.
Also, multisig with just a single seedsigner is an amazing user experience so it depends how you view that as well.
