To answer the original question: I think adding as many of the hacks as possible would be the way to go. There's been some really clever ones created over the last few months (my favorite being the ignore users/killfile).
Cleaning all the hacks up, optimizing them, and rolling them out into the main distribution would be terrific.
I'd prefer if all the hacks were optional though, and they be split up into seperate files whenever possible and appropriate-- to keep server load down to a minimum.
