We want to have the ability to fall back to legacy GL contexts when creating them. In order to do so, we need to store the legacy bit on the GdkGLContext, as well as being able to query it. Setting the legacy bit from outside GDK is not possible; we cannot create GL contexts in 3.2 core profile *and* compatibility modes at the same time, and if we allowed users to select the legacy mode themselves, it would break the creation of the GdkWindow's paint GL context. What we do allow is falling back to legacy GL context if the platform does not support 3.2 core profiles — for instance, on older GPUs or inside virtualized environments. We are also going to use the legacy bit internally, to choose which GL API we can use when drawing GL content. https://bugzilla.gnome.org/show_bug.cgi?id=756142
