One thing you need to clarify is the relation between your work and FIDO2/WebAuthentication since the latter is the only thing the platform vendors [currently] plan to support out of the box.

If you rely on custom client software, you are likely to face adoption hurdles.  Personally, I'm singularly targeting "phones" as credential holders.  Unfortunately, if you don't buy 100% into the FIDO2/WebAuthentication paradigm (I don't since its domain centric model requires IdPs to scale), you end up with imperfections like QR codes for interacting with desktop Web applications.

In my opinion SSID can't be seen as a "killer app" because it's much more than an app, it's a paradigm (built over a set of interconnected platforms) in which blockhain technology is a key component at this point. "Killer apps" will be built /on top/ of SSID platforms, and these are what will give "life" to SSID (and its underlying technologies) through empowering individuals and organizations with regard to identity ownership. Once /identity owners/ are empowered through self-sovereign applications, the current systems that operate around identity will have no choice but to adopt, adapt and contribute. This is not too different from the role of cryptocurrency in the context of financial activity. This "adaptation" is a process, though, quite unlikely to happen abruptly.
> SSID in itself is a concept and a paradigm, sort of a "meta-app" so to speak, no one will "buy" it as such. Yet it's a recognized necessity on the digital world, and IMO its "essence" will remain even if its underlying technology shifts from blockchain to a different (probably more efficient) thing. What seems to matter is decentralization, immutability and sound cryptographic proof mechanisms. Presently, DLT is the most obvious answer to our implementation needs, and surely this might not be the case forever. In any case, the need for things like decentralized identity (along with decentralized money, etc.) will remain regardless of the technical paradigm that sustains them... Blockchain is an opening gate to a conceptual space of empowerment through decentralization and trust in mathematics /in lieu/ of authorities, and this "space" is what is "alive", it can (and most probably will) take many shapes in the future, but there's still *much* to learn and do on its current
