At this time this is my understanding:
KB2919355 has been revised to fix the main cause of failure, the corruption issue. That's that clearcompression flag patch you see in the revised KB2919355.
Any of the other threads started to deal with the other known issues (see http://www.infoworld.com/t/microsoft-windows/microsoft-posts-tips-overcoming-windows-81-update-kb-2919355-errors-242603 for the links to posts in this forum) I do not see any action from said software company to fix these automatically. I have been given no information that any automatic fix is coming. As is stated in all of those links, if you are still impacted, you are informed to contact support directly.
That's the current "resolution" at this time.
On a similar note, may I share a support story? Yesterday I had a problem updating my mini jambox speaker. I called support. Talked to a nice person who I told him all the steps I had done. He said "yes, you've tried everything, let's get you with an escalation case". I received a call back, from a equally nice person, who walked me through a factory reset. The update to the Jambox then took this time. I had to reset the device, but I lost no data. Obviously a jambox speaker is not the same as a Windows 8.1 but I think the problem is exactly what you said at the end "the dynamics have changed and people have become accustomed to this sort of incompetence and it is what they expect from most businesses nowadays. "
I was shocked by my good experience of support with the Jambox device. I shouldn't be shocked. I should expect this from all my vendors.
