So that means, it is irrelevant what we set for Z-seam alignment?

No, z-seam alignment settings will still have an influence as before but the difference is that now it will no longer start a new layer where the previous layer finished when z-seam is set to closest.

Now it is multi-threaded, all layers start at the same location. Arguably, that is a regression but that's progress for you.
Multithreading is a very useful feature, it makes slicing faster, but sometimes (like in this case) I prefer a longer slicing time if I can save an hour or more in a 25h print.

I agree that it would be good if you could choose between faster slicing and better quality output.

I agree too. I have tested an object using Cura 3.4.1 and Cura 2.3.1. The result is that Cura 2.3.1 does a faster printing:
This is the test object:
This is the slicing in Cura 3.4.1, you can see that there are 2 travels for each layer (printing time 9h26m):
And this is the slicing using Cura 2.3.1, only 1 travel per layer because it's starting every layer where the previous one was finished):
The result is that Cura 2.3.1 is faster at printing, the difference is not very high but this was only a test object. More complex objects could have a bigger print time difference.
Yes, but it is how it is. We have to live with the current behaviour. You can open an issue on github and complain about it but I doubt if it will get acted upon.

And what about the first thing I noticed, it is really strange that Cura will travel to a far island when it has others nearby. I have already posted the issue.
Let's see what people on Github do.
