The 200 ms delay before debouncing the PHY was introduced for some buggy old controllers. To decrease the boot time to come closer do instant boot, add a parameter so users can override that delay. The current implementation has several drawbacks, and is just a proof of concept, which some experienced Linux kernel developer can probably implement in a better way. One problem is, that the warning is shown for each link and not just per controller.
