As someone who also studies electronics, I completely understand your frustration. The mechanical structure of the Pi 5 has indeed regressed, especially the fragile lock design of the USB ports - the batch we bought for our lab last year had similar issues.
Regarding maintenance:
Technically, it is completely feasible to replace them (the 0402 solder joints are not too difficult), but a hot air gun and a microscope are needed. Novices are indeed prone to damaging the PCB pads.
A more practical solution is to buy a USB 3.0 expansion board and transfer through GPIO. It is more reliable than repairing the original port (I have two in my drawer).
It is recommended to directly contact RS Components/Raspberry Pi official. They have a fast replacement channel for bulk purchase users recently. Also... remember to apply some 704 silicone to reinforce the interface next time (a secret recipe passed down in the laboratory).
PS: The issue you mentioned about Sony's subcontracting is quite interesting. Their PCB coating process did change after 22 years...![:lol:]( "Laughing")
