you won't have to do this anymore
Correct. We use NIP-07 on computers but mobile devices do not have that luxury. This will make everyone and everything be more secure.
exactly, no more extensions
I think very few people will use this. Running your own hardware to sign events is way beyond most people.
embassyOS, umbrel, etc make it easy; I plan on dockerize this
and businesses for sure will
Nice
Making this a docker container and packaged on start9, Umbrel, myNode, etc, with a nice interface will make every single node runner out there be able to do this with the click of a button. If you're running a Lightning node, you'll run this too, IMO.
exactly; if you're running an LN node you already have a device you are trusting with hot keys
