Recalling that was possible in previous versions of rpcs3 interpret VP and FP images with OpenGL 3.3, since the hardware of the Playstation 3 is based on NVIDIA G70 thus may not require as current video hardware.
"... thus may not require as current video hardware."
We probably wont have hardware that will run PS3 games OK for another 5 years.
By the time we'll run most PS3, everybody will probably running OpenGL 6 or "OpenGL Next". And considering that OpenGL 4.2 is already quite old - it was released on August 8, 2011. Also often newer version of OpenGL have some new features that we can use to emulate something that was on PS3. Why we moved to OpenGL 4.2 is because it has some new instructions for the Shader Program, which were on PS3 and used by many games. Without those additions that were made in OpenGL 4.2 the developers would spend more time working on custom implementations of these instructions, when they could be working on more important stuff like trying to reverse engineer RSX.
TL;DR: Doing some things in OpenGL 4.2 is easier, takes less time and isn't worth of a custom implementation for older hardware, which most likely wont run any good games anyway.
