My big concern is that somebody plugs a panel in plus two high-amp appliances, like a space heater and a microwave, in a sequence that means they don’t trip a breaker.
No there is a real concern there. Suppose you have a daisy chain that goes breaker - PV panel - load. Say you have 20A draw on the load - enough to trip a 15A breaker, but the PV is providing 10A. In that case you only have 10A at the breaker, but your wires will be significantly over-current.
I think the issue is that, if you have a circuit designed and protected for X, then put Y solar in, you can get a situation where X+Y is flowing down some of the wires. It’s more than they are rated for, but the breaker doesn’t see it.

I mean, yes. That’s how I make my living, im an electrician. But once again, supplying 10 amps is really not a risk in the majority of cases imo

Microwave on a dedicated circuit above counter in kitchens and gfci protected per code
You’re not putting a space heater on your kitchen counter
And once again youre supplying up to 1200w, not drawing 1200w. Any power supply system will just be matching the load being drawn
I really dont think this is the degree of a problem you think it is
