It can't (well, if it really really wants to, it can add some code to
its own foo-mode-hook which is run after text-mode-hook).

A function added to a mode hook takes precedence, because it's presumably
a user choice, whereas body-of-foo-mode is the choice of code's author.

If the user doesn't want auto-fill-mode in foo-mode, she can add to
foo-mode-hook to turn auto-fill-mode off, or she can change her
text-mode-hook to test (derived-mode-p 'foo-mode) before enabling
