As long as Debian keeps i386 architecture, it's not a big problem.
I do have some legacy computers (32-bit CPU without PAE) running i386 version of Debian testing. The only problem is that the very-old Intel integrated graphics (830GM for X30 and 855GM for X40, respectively) are not well supported by the i915 driver, so I could only use light-weight desktop environments like Xfce or MATE.
