(t) makes sense, I'd say.

It's not a change to semantics though, just the default value.  And
starting from the current default of t, if some code does
(add-to-invisibility-spec 'foo) followed by
(remove-from-invisibility-spec 'foo) you get (t), so arguably just
starting from there in the first place makes things less confusing than
they are now.
