I think the biggest driver here is cost more than anything, and on that point I think we're stuck with them, even as the trendiness of them fades. As long as open-plan offices allow you to cram more people per square foot than other designs, companies will stick with them because lowering OpEx is more important than improving unmeasurables. As you said, if there were some way to accurately and unarguably measure productivity loss in dollars, we'd probably see this trend reverse, but until then it's liable to stick around.

The only hopeful note here is that some of the early adopters have started to move away from it, and industrial designers have started to come up with people-dense but less productivity-destroying designs (e.g. https://www.steelcase.com/quiet-spaces/)
