OpenGl ARB_base_instance extension not supported ?

[Graou]

Hi,
I would have liked to use the services of the ARB_base_instance extension but there are some symptoms which make me believe that it is not supported.
I was able to see this directly in runtime or by querying the list of supported extensions.
Is it a desire specific to LWJGL to ignore this extension, an implementation still to be done or a potential problem on the side of my environment?
The LWJGL versions I tested are 3.3.2 to 3.3.3+5 and the OpenGl version is 4.1 ATI-4.14.1.
