Here's the thing about CLEO sign-off. When you have some people in the state who can't get NFA items because their CLEO is politically opposed to NFA, you have a defacto geographical ban. It's ******** when person A can have NFA and person B can't simply because they live on different sides of a county line.
As it currently sits, the trust route provides a way to bypass CLEO sign-off but the ATF is considering enacting the 41P rule changes which would require CLEO sign-off on trusts too. That was supposed to be decided on in May, but it looks like they have delayed the decision again. NFA has some pretty extensive background checks, more so than a simple 4473. Shall-issue didn't create a wave of gun crime, shall-sign sure as hell wouldn't either. Pretty sure criminals aren't going to submit a form 1 or 4, pay a $200 tax and wait several months to obtain a suppressor.
