what worries me is that it shuts down current before trying other things to reduce load [such throttling] and, the louder complaint, that all documentation say the it would limit the usb output to 0,6A but no mention on the output on the PCIe bus [confirmed that if you start via USB you get on boot a loud remind, but nothing if you start from PCIe ...]Would you rather have the Pi dump all the available current through a short, start a fire, and burn down your house? With no protection on the PI you're relying on the RCD or fuse in the plug or breaker panel to protect you.
You Pi does not, and cannot, know if the over current it detects is peaking at a few (tens?) of mA or it's the start of a much larger draw. It seems the designers have decided to err on the side of caution and cut power to down stream USB devices before damage can occur to the Pi, the PSU, your home's wiring, life, and limb. A sensible thing to do in my opinion.
For your soul's peace: there is an overload breaker in the socket where my PSU is plugged.
