That is the industry standard, although some companies may not even offer a 90 day part warranty while others may offer longer depending on the part replaced. I'm not really aware of computer OEM offering more than a 90 part warranty with some not even offering any part warranty.
FYI, the Logic Boards on the 2016+ Macs have become more complex since Apple has taken to integrate formerly smaller separate parts onto these Logic Boards. While Apple integrated the memory into the Logic Boards back in 2012 with the first Retina models, beginning with the 2016+ models, the SSD & WiFi are not also an integrated part of the Logic Board. In addition to that, the security enclave chips has been added to the Logic Boards introducing another point of failure since the security enclave chip has ties to all major parts of the hardware and macOS. Even the USB-C ports are more complex than older style ports such as the older style USB ports & video ports since many USB & Thunderbolt features are now tied more closely to the CPU and these USB-C ports can be used to supply power to the laptop. All this adds more chances to have the Logic Board damaged by connected devices since all the safety circuitry is on the Logic Board.
Don't expect Apple to reverse any of this since everything we've seen Apple doing over the last decade points to them continuing in this direction with their computers becoming more & more like an iPhone or iPad.
Check with your local consumer protections laws to see if any of them apply to your case.
