Tbh I've been meaning to do this for a while & it's really helping my mental health not to scroll. I'll be back on occasion but nowhere near as often as I used to be. Catch me working on my house or working out at the gym or going for a hike. Life is better when you ignore things you can't change.

I do only use it a couple of times a week so I'm not a very heavy user, but I still can't wait to electrify it (and my furnace) and get off gas entirely.

(I actually do have a class B CDL so am in theory also fully qualified to drive a garbage truck, so maybe bad example.)

IEEE 1547 governs DER connections, I'm sure this stuff can be added if it's not in there already.

All of the new reclosers I've been working with come with dead-line checking by default, which makes sure to avoid closing into an unsynchronized island. It's a bit harder with substation breakers though, since you need PTs on the getaway and those aren't free.

IEEE 1547 (iirc) requires inverters to trip within 2 seconds of losing grid power, so changing the standard first reclose interval from <1 second to >2 seconds could definitely work as a band-aid fix. Voltage regulators, it's a pretty simple change to just block stepping when in reverse power flow.

Fwiw I own guns for a completely different reason: I live in the middle of nowhere and going to the range is 1 of about 6 activities to do out of the house around here. Why deprive myself of 17% of my activities?

Definitely agree there. If I have to choose between slower Netflix or losing my air conditioning during a heat wave, I'm picking the slower Netflix every single time.

I strayed away from my beloved flavor blasted last week and had the parmesan ones, and honestly they were pretty bland. Gimme that xtra cheddar any day of the week.

That's basically to stop a circuit breaker or recloser from closing in on a circuit that's still energized but not synchronized. Closing in out of phase is bad news, and the even worse bit is that in a situation of inverters vs the big grid, the big grid wins and your inverter fries.

Though I will say as an EE at a utility, it won't be truly permissionless. You'll have to submit a thing to the utility where they'll check your circuit to make sure no protective devices are getting backfed that don't have the ability to be backfed. But that's probably automatable.
