In legacy/trac#16005 we made use of the miminal WebGL mode as a middle-ground for allowing WebGL while not being exposed to its fingerprinting capabilities. Now that WebGL2 is available (see legacy/trac#16404) we could think about doing something similar with the information exposed with it. However, it is not sure whether that is a viable solution at all for at least two reasons: 1) There is no minimal mode in WebGL2 which would help us. 2) WebGL2 provides probably more powerful and resource-hungry features. Harmonizing them across older and newer computers while keeping them still usable might be tricky.
