I mean, if you want go that route, even Google has "~all":

[9:04:41] t15-6:klausa:~ $ dig +short txt gmail.com
"globalsign-smime-dv=CDYX+XFHUw2wml6/Gb8+59BsH31KzUr6c1l2BPvqKX8="
"v=spf1 redirect=_spf.google.com"
[9:04:43] t15-6:klausa:~ $ dig +short txt _spf.google.com
"v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all"

I think you'd be hard-pressed to argue that Google doesn't have "enough control of" their email infrastracture...
