Makes sense to me and will do to anyone in the know about kitchens.
Regarding the edging, most cheaper carcases will have thin melamine edging which can get chipped off the front of the carcase/shelf. Better quality ones will have 2mm ABS with a radius to the edges which if far less likely to catch but not really an option for home fitting as you need a glue pot edger.
Don't know what you are using to cut the boards but the faced MDF does tend to chip out less than chipboard, think of using both, the MFC for the carcase where the break out won't show and MF MDF for shelves and vertical dividers where both sides of the cut show.
