Maybe the groups can be controllable. For example:
(defcustom mm-w3m-safe-groups "\\`nnrss[+:]"
"Groups in which html articles are considered all safe.
The value may be a regexp matching those groups, a list of group names,
or nil. This overrides `mm-w3m-safe-url-regexp'.")
That looks good and easy to implement, though I have no time for
the moment.

BTW, don't all you know the way to access unsafe links? That is
`C-u RET' on links in html articles.

P.S. I'm going to go to the business trip, so I may not have time
to read news for some time.
