Given that the guidelines in question are somewhat subjective, I don't see this having a particularly significant effect on the current deportation practices. The thing that could be interesting here would be using this as precedence for preventing some jurisdictions from attempting to impose stricter arrest policies on other jurisdictions. Such an example might be states trying to force other states to enforce abortion bans on citizens across state lines or drug possession laws.
