Phones with QWERTY keyboards are still made, but unfortunately they're produced in such limited quantity that they're not built with high-end SoCs. The F(x)tec Pro¹ and the Unihertz Titan just don't take off enough to warrant big investments. There's a group of Android users who prefer physical keyboards (that I too belong to as well), but it's small. Even when physical keyboard died, people sold QWERTY keyboard covers and cases for some smartphones (I think the S6 Edge was the last one with an official keyboard?) but even those have died out because of lack of interest. In theory, all you need to add a sliding keyboard to a modern Android phone is a corner USB-C connector and a sufficiently sized case. Someone skilled with 3D printing and circuit board design may just be able to build one for their phones if they can get their hands on the keyboards themselves...
