Highly recommend them for any repair/replacement issues you may want to tackle yourself.
Easy repairability requires added size, weight and complexity. iFixit is great, but Apple is just going in a direction that’s not very friendly to home fixing, with extremely tight integration and packaging of the devices.
It used to be you could even upgrade the chip in an XBox. Not anymore, now the 360 has a new chip and in later versions the system is on one integrated chip, totally non-repairable.
