Mostly the hassle involved to extend the cabinet (color matching, retrofitting, etc), but also the super tight clearance. I already had to cut a notch out of the drawer to clear the range knobs, and even then I still have to open the oven to clear the handle.

I could do a blind cabinet, but I feel like it’s not the optimal use of the space, since those pullout solutions tend not to utilize the full space. That’s why I was leaning towards a short water heater or extending the lower portion of the linen closet on the other side of the wall.
