It most certainly matters what you do personally. What that might mean in consequence is that you decide to buy a cheaper house than you could maximally afford, put a greater percent down, or you might delay buying a house for a while.
The differences among households' incomes are already higher than the reasonable ratio between the max approvable to borrow and the sensible amount to borrow. (A household making $300K can already sensibly borrow more than one making $100K can be approved for and one making $100K can sensibly borrow more than someone making $30K can be approved for.)
Households are still competing with others to buy individual properties, of course. That competition doesn't mean that you should YOLO it with the largest purchase most people will ever make just because others are willing to do so.
