I found this here:

It depends on what your goal is.  If you want to deter spammers from using
your domains, then -all is a good idea.

OK, now please explain why someone would want to use ~all as google
suggests?  Yeah, sure, while testing it is OK, but thereafter ?

Probably because adopters of Google's SAAS email service typically do
so gradually rather than 'big-bang', and during transition (or perhaps
even permanently) still send email from their 'legacy' systems as well
as from Gmail. They'll have a history of support tickets around this,
which will have led to the ~all advice.
