Looking back at some older kernels, that code seems to have setup an
ebda region only if there was a non-zero real mode pointer at 0x40E.

This is rather different than always setting up such a region.

I would hesitate myself to re-introduce that code, because I know
too little, and have no pressing need for it.

I will leave to others the desirability of such a change.
