I'm not saying it's impossible for OS to eventually arrive at the correct end state, just that it's impossible to do what I asked.
While I appreciate the alternatives proposed by others, they are all bad fits for various reasons.
I'd rather deal with it in source or via some kind of metadata integration than turn a clean *:* rule profile into something that no one in the company but me will ever be able to decipher. The complex expression was a minimal dozen lines of code with built in comments/documentation but it turns out that won't work.
So, I'll figure out another way.
