Doesn't that make it more or less standard? It's certainly more standard than anything else, isn't it?

Can you show a better or more typical "standard" ciruit? I think not.

I admit it may not be very good for some things, but it was used almost universally from 1977 to sometime in the early '90's with great success. It's just been the use of wall-warts and vastly inadequate switchers that's caused all the attention to be focused on the shortcomings of that reset circuit.

No disagreement with the proposition that a supervisor does it better, but ... if the Vcc came up to legal levels within < 1 ms, and wend down below 0.5 volts within < 10 us, I suspect all the problems associated with this inherently weak (because it's positive-going) reset circuit and this inheently stupid MCU hardware design would go away and be forgotten.
