Would it be a plus to attach a cord of some sort to the back wall and to the sliding shelf to limit it from sliding all the way out and dropping the oven and causing harm to itself and the one pulling the shelf. Perhaps install a releasing hook of some sort on the self end of the cord to allow removal of the shelf is so desired.
Also a latch to keep the shelf from sliding out during travel.
I like the idea of the slide saving wasted space that typical drawer slides require. It appears there is a gain of 44 cubic inches of storage in a 6 inch high and 22 inch deep drawer. 58.7 cubic inches gained with an 8 inch high drawer. That is a significant gain on a total cabinet install.
