Chromebook to the "rescue"

I've already worn out my keys on this one, but I find the refusal (it's a "design decision") to support most recently used (MRU) tab switching order in the Chrome browser to be extremely frustrating and obstinate. I am quite often trying to switch back and forth between two or three tabs within a larger open tab set. And so are many others, apparently, from all the comments online on this topic.

What happened to recognizing and supporting how people actually work?

Yes, there are extensions that kind of get around this, but the Chrome security model prevents their hooking Control-(Shift-)-Tab.
