That's kinda the point of PopOS in the first place: retrofitting GNOME and Ubuntu with extra utilities for a better "out of the box" experience. Manjaro does basically the same thing on the Arch side of the fence, and both are essential to providing that experience you're describing. The GNOME team isn't intentionally holding back features or making intentionally bad choices here, they're just part of the brick in the wall. The GNOME desktop should be bland, so that the distro can provide a default and the end user can make changes where necessary. It's all part of one big machine.
