How much robustness do we really want?

You can't have too much go right, that's an unrealistic goal.

Why reimplement something that exists? Can we reuse single user mode?
Why do we need single user mode at all?

If you're changing something as important as the init system, one should
be prepared to have an system rescue medium available to correct the
system if needed; although that is not necessarily needed if you use a
wrapper with init=/sbin/einit as you can then just drop that kernel
parameter and use the default again.

A comparison between methods goes further than just calling the other
methods broken; this doesn't make me see your method as better, but
rather as just another method, perhaps even a broken method.

You're making a lot of statements like this but don't back them up.

Why would this work best for this situation? What's wrong with the rest?
