~all is perfectly safe for production, it's in the wizard...  I'm not
going to sit here and explain to you how SPF works, although I will say
you are partially right. The wizard defaults to either ? or ~, as a
matter of fact, anybody who has ever used SPF should know that if you
are on mailing lists (like this one) you should be using ~all unless you
plan to add "a:chlorine.canonical.com"

SPF checks go to the record of the last server in the chain sending the
email, not the IP of the the user sending the email to the server, so
adding my computers current IP would be ignorant and a waste unless I'm
running an SMTP server on my computer, which I would never do
considering I have my own servers and I pay for 2 other providers to
give me backups, one of whom is obvious because I prefer to use their
SMTP servers. It also doesn't help that Canonical is forwarding email on
our behalf and I do not have them whitelisted either.

Reiteration: You do not have your *personal* IP in your SPF. And you are
wrong, it's soft-failing because I do not have Canonicals servers in my
SPF record.  Read:

Hey check that out. Get it? I'm real! I'm not spam, I'm ham!
Also, the average user should be using:

v=spf1 a:domain.tld/20 ~all
v=spf1 mx a:domain.tld/20 ~all
v=spf1 include:_spf.google.com ~all (as Google puts it)
