I feel like you've maybe had the benefit of working in teams where this didn't happen.

I've seen it first hand, people cotton on to EM's latest buzz word, find some space to shove it into and then show it off. EM is blown away despite the result being over engineered or poor fit for the solution.

Last time I saw this was a system decomposed to events when tight orchestration was necessary. 10 months later a single function app was dropped in place to replace it. Dev who did the original work got a promotion for their gift of technical debt.
