I'm not afraid of speaking up and getting smacked by the next update. If you ARE afraid of speaking up because you might get hit by the next update my advice would be to start fixing your site now.
It's easy to not be concerned about speaking up when you don't participate in controversial threads or express strong opinions. But for more outspoken members, such as me oftentimes, I become a target for those wanting revenge. So by participating in threads where I can't absolutely prove something other than say "I feel strongly about this" I leave myself wide open to verbal assault. I don't need that, it disturbs my inner peace. I'm not afraid of comments about the updates themselves, actually the word fear doesn't hold me in it's grip, I simply know when I should leave well enough alone.
There are no tactics Google doesn't know about, just ones they haven't dealt with yet.
If you are referring to offsite tactics maybe so but there are definitely onsite optimizations that they will never be able to refine enough for, nor have they even taken it into consideration.
Based on my point about being controversial here's an example of me sticking my hand in the fire unnecessarily. I'll go so far as to speculate that when a site exceeds their algorithm's capability of containing it within their predefined limits they will write an exception to push it back down until they can reverse engineer what the site owner did to exceed their predefined score sheet by XX%.
