Since the Pi4 hardware is different, I don't see the point in maintaining backward compatibility with units that will surely be scrapped fairly soon anyway as people upgrade to the Pi4.
There are millions of more Pi's out there which are not Pi 4's than are, and many millions which cannot use 64-bit. And I would expect most don't get junked or land-filled as new Pi's arrive but continue to be used or pass into other hands.
Older Pi's are still perfectly usable and there's no compelling need to upgrade in many cases. Many have a long useful life ahead of them.
The need to support 32-bit will continue for a good while yet unless the RPT/RPF are prepared to simply drop support for their legacy customers and face the inevitable backlash which will come with that - which they sensibly don't appear to want to do.
There may come a time when Pi is 64-bit only, when 32-bit Pi's becomes historical artefacts, display piece novelties, or have made their way onto a mountain of recyclables, but I don't expect that to be any time soon.
