Professional software developers have a lot to do just to get their job done on time and within budget. Having to duplicate all their code just so that people who contribute nothing to the end product can have an easy time understanding it is just never going to be a priority worth addressing.

The problem here is not really the code, it's the reader.

Who says they have to duplicate it? Just write the original version clean, clearly, and concisely. Then run it through a mangler to rename variables to avoid collisions.

The STL is maintained by volunteers, it's a FOSS project. So your appeal to Serious Business doesn't hold.
