Okay, which brings me back to what I just said... what exactly are they waiting for that at least 76% of the rest of the country (per @Clonefan32) didn't see a reason to hold off on?
There is 150+ pages of debate on whether or not an SIP actually means anything. I'd guess the debate falls along those lines.
As I've said 100 times now, do the SIP. I don't care. I'm all for it. But be reasonable about it's practical impact. Read the orders that exist. Every business that is currently operating will have at least some claim to being essential.
It's a difference without a distinction.
