Incomplete Sets

I'm endlessly frustrated with incomplete furniture sets

• Fences without a matching gate
• Kitchen counters without matching upper cabinets (preferably with a matching slotable drink bar for each counter set)
• Incomplete appliance sets (ie. fridge and stove but no dishwasher)
• Incomplete bathroom sets (ie. shower/tub and sink but no toilet)
• Dining Table sets (just make a 1x1 2x1 and 3x1 of the same table)
• Arm chairs/sofas/loveseats (please just make all three and not just one or two)
• The list goes on and on

Why does the Sims team do this? It just seems so lazy and careless.
