Because both code paths require the existence of `GL_TIMESTAMP[_EXT]` which is only guaranteed if `ARB_timer_query` (included in GL core 3.3) is implemented. We know when that is true because `context->glGenQueries` and `context->glQueryCounter` are non-NULL. So that is the minimum requirement for any use of `GL_TIMESTAMP`, even when it is used in `glGetInteger64v`. Until now, Raspberry Pi (OpenGL 2.1) would find a working implementation of `glGetInteger64v` but failed to check whether the driver understands `GL_TIMESTAMP` (it doesn't).
