I don't think you missed something. If anything, site-locals are even more
complex to support than you suggest. But site-locals (or, more generally,
scoped addresses) are what we got in the face of the questionable assertion
that provider-independent global/routable addresses are too difficult to even
think about supporting.
As long as we are stuck with a totally non-scalable address allocation
system (remember, provider-based aggregated addressing consumes address
space *exponentially* in the number of providers in the service chain)
end users need some way to provision local systems with stable addresses.
So far, nobody has proposed a viable alternative to scoped addresses.
