Around the time of OpenGL 3.0, they added FBO's (FrameBuffer Objects),
which allowed rendering directly into a texture without needing to use
glReadPixels followed by glTexImage2D.

 That doesn’t help, because those FBOs are intended to be used as textures
for further rendering on-screen.

Granted, but one can leave the final ReadPixels for when they want the output image, and use FBOs internally for things like cubemaps, reflections, shadow maps, ...
