SSH doesn’t rely on PKI. Using SSH certificates is a password replacement for accessing remote services. While it is a kind of identity verification, its purpose is not the same an application signing. Self signing is open to too much abuse. The whole point of signing is that the provenance can be verified (yes, checksums are a thing) and that the signing can be revoked should something bad happen. Notarising code is the process of a third party verifying your identity. So rather than saying, “hey, you can trust me”, you are asking a third party to vet and prove that you are trustworthy. If you can’t see the value in that for all parties - including the most important party, your customers - then that’s up to you. No sane SOC will allow unsigned or self-signed binaries. Consumers with the slightest bit of savvy will not run unsigned or self-signed binaries, and OS vendors need to take care of the rest. Thinking of the Confidentiality, Integrity and Availability triad, your solution is unworkable.
