Depends what you mean by "the remainder of the world". Most mid-tier companies I've worked at or know people who work at in London started moving on from microservices some time ago. So I guess, unsurprisingly, no.
Are we talking about the same London? The market is still flooded with engineering playgrounds and microservices are still considered a perk and bragging point by many companies.
Finding a company with a sane tech stack that doesn't do complexity for the sake of complexity is impossible. It makes sense though - those companies already have their developers, they are happy and the company doesn't need to hire more.
