While a valid, this one has, I feel, less chance of getting through the political machine and ever happening. It’s too easy to oppose it in bad faith with arguments like “they want murderers to go free because we can’t prove they <insert a derisive related minor charge here, like stealing, or jaywalking>

It’s harder to argue against “not bringing bullshit charges” even though in practice the outcome of your version would simply be the lawyers/prosecutors don’t bring bullshit, it’s the political downside that, I suspect, would doom it.
