While I'll remain neutral about the specifics of SPF (and all the other
solutions), the legacy problem comes up trying to secure any thing. If
it (and I deliberately leave "it" undefined) had never worked, no one
would complain. Of course, there will always be someone who goes too one
extreme or the other extreme. People were dropping heavily spoofed
domains before SPF anyway.
At what point do we consider legacy support not worth it? It took 10+
years, but now almost no SMTP servers allow open relay by default. Will
it take another 10+ years to stop supporting misconfigured migratory
laptops by default?
