I come from industrial electronics design background, so my knee-jerk reaction to this is, “no”. These features work off DC, provided by simple and cheap voltage regulators, and easily cleaned up with a few capacitors. It’s terrible design, in my world, to leave a circuit vulnerable to this.
But then I have to remember consumer electronics is all about shaving pennies, or even fractions of pennies, and capacitors cost money in both direct cost and PCB real estate. Heck, even the days of extra R&D work to characterize and test the circuit against such power anomalies could be a factor. So, compromises will be made, not by accident.
I hear you from a circuit standpoint, but so many electrical surges now, either home generated by a/c compressors or spikes in line.
power here often goes off and back on in seconds. I would love to have an oscilloscope and THD analyzer on the line when that happens.
Get hit by lightning and most electronics are poorly protected.
my nephew has a microwave oven with a push button motorized drawer. With a color screen. And wifi.

I remember the first Amana Radarange that came into our area, friend of my parents had one.
Looked like the front end of a 56 Buick. Massive heavy chrome thing.
we've come a long way.
Of course like many of you I know what a hand wringer on a washing tub is.
Ask a Gen Z how to operate that and I bet they think it makes pizza.
But given any kind of care at all, it's still working.
it's remarkable how many advances we have made in both output and reducing size.
And for sure cost.
WinterDeere, I used to own my little town's Radio Shack. I've seen a lot of broken retail electronics.
that's where I learned
if you teach it to drink it will soon learn to smoke
industrial: how can I make it better and more MTBF
retail: how can I make it attractive yet cheap as possible to sell at a certain price point
I have seen some great electronic designs. I sold hundreds of Sony Trinitrons and only got one back, the one with the built in VCR that
someone had jammed a tape in. But those Sony tubes, bless their heavy weight, were super reliable.
I just wonder if my OLED Samsung will last as long.
Now I do admit to giving every Sony tv customer a free single outlet surge protector as part of the sale.
Always wondered if that was a big factor in reliability.
from memory, only other expensive electronics I sold that never came back for repair were the early Motorola and Panasonic
bag phones. Contractor phones for the front seat of the boss's truck. Then later early adopters for cars.
Those phones were likely built almost to milspec, they were heavy, tough and rarely broke.
They just became dinosaurs technologically and could not be upgraded further.
And there was always the customer who wanted the first Motorola hand held cell phone
