buffer enable() and is_enable() callbacks unused?

Hi,

Currently none of the buffer implementations implements the enable() or is_enable() nor does core code try to call these. Is this a left over and can be removed or is there a plan to make use of them in the future?

Thanks

Odd indeed. No plans to use them from my side anyway. Must be some left over from an ancient rework.

Feel free to scrap them!
