What sort of statistics do we track that would be impacted by this change?

(to me it doesn't seem like this feature would improve coverage, etc - partly mechanically (this adds new tags we might not have any stats for) and partly practically (knowing the value of the parameter in the caller doesn't necessarily mean you know the value of the parameter at various points in the callee - parameters are usually mutable, so the callee might've modified the parameter & the callee's value won't reflect that))
