Summary

some software/games,
require normal maps that have an inverse y of what blender produces,
ordinarily you would have to open the rendered image in another program such as gimp to invert the green channel
of the image , or set up a node system.
this is a small addition to give the user a choice while rendering out the normal map(tangent)

it is something that would save time, and allow users to stay in blender longer while creating assets.

hope you find it useful.

Didn't look deep enough yet, but two things are:

We do have channel inversion operations in the image editor. This is better be discussed with more artists.
Even if we decide this functionality is nice to have you're still to make the same for multires and cycles bakers.

Woops. Misformatted the reply a bit.

What i meant is: the need of this buttons better to be discussed with other artists. For now i don't think it's so much common pipeline and it could easily be done in the image editor.

sergey,
i will make sure to act on
"Even if we decide this functionality is nice to have you're still to make the same for multires and cycles bakers."
so if it is decided to be useful that will be done.

thankyou for looking.
