OpenGL 2.1 is not enough for browsers - Firefox requires OpenGL 3.2 for limited hardware acceleration support, and there will be limitations on Chrome as well. Desktop acceleration is a similar story, KWin will have a degraded experience for OpenGL less than 3. There is also the possibility of breakage due to missing extensions. Most old games won't work because most are going to require OpenGL>=3. For D3D games from Windows, translation efforts have long been focused on Vulkan, and even then, you are very likely to require extensions which aren't present or further versions of OpenGL. So that's to say that, it's not about AAA games, it's about Firefox, (full) KDE, and Minecraft. Which is going to take a few years, probably. There is no RIP, it's going about as well as those people were predicting - I'm expecting it's not going to be able to have full browser acceleration and play Minecraft until 2 more years at the very least.
