> Text files are inherently GPU-hostile, and that makes them a weird choice for a graphical markup language.
The point of a standard is to be device agnostic. Tying it to present-day technical implementations would limit its adaptability to future tools, as well as creative misuse of the technology.
Then why tie the format to present-day technical tools like text editors? Why not invest in a format that makes sense and the tools to understand and work with it?
Also, GPUs and their architecture aren't a fad, they have been the same for the last 30 years. If you want your format to be truly device agnostic, text is a bad format because it precludes many types of devices (GPUs and hardware accelerators) from being able to use it.
