Are Agile Testers Still a Thing?

We need our testers in agile. See, they have a post it.

With the implementation of Agile methodologies and the coupling of roles in software development, the tester has been lost, especially since integrated roles like the full stack developer started to emerge. Companies are looking for people capable of performing analysis, design, architecture, development, and testing, grouping these skills into one single specialist.

But don’t all these roles have to be taken into account for software development? Although there are those developers with extensive knowledge who are capable of performing functions in each of these areas, there is always a role that loses some importance.
