Default Disable capacitive button light ?

It's been 4 years of Galaxy S I9000 and no developer has yet developed a method to turn off the capacitive button light. This is very necessary as it could help with the very low battery capacity. I strongly request developers to concentrate their skills on this, to disable the light and thereby prevent the irritation to eye during the night & save a lot of juice.
Please Help
Thanks
