I would only call it a disgrace if the issue did not appear in testing yet appeared for a large number of users or if Apple released and update where problems appeared during testing.
Keep in mind these upgrades are being done to an OS that has a unique history based upon how the computer was used in the past. Issues that did not appear in testing are going to come up after release. Then there is the potential defects in the manufacture of a particular unit or due to how it was handled. In other words, it is legitimate to miss an uncommon fault.
As for Arch, I understand why the warnings exist. That being said, I have found it to be very reliable. I typically attribute it to changes being incremental, meaning that problems are less likely to arise; and due to development being done in the open, resulting in a larger pool of testers before it even hits rolling distributions like Arch (never mind distributions that do their own testing).
