That's an odd statement. How are those two things related?
You can still run 32-bit binaries (including thumb-2) under 64-bit OS in 32-bit execution state -- as long as kernel is configured to use 4kB pages. So your usermode binaries don't need to be bigger.
Or you can take advantage of higher performing 64-bit mode.
(Unrelated, but my pet peeve, one thing a lot of people get wrong: 32-bit ARM (Aarch32 and most ARMv7) supports 1 TB of physical RAM and 64-bit IIRC 16 TB. Not sure where the idea 32-bit ARM could only support 4 GB comes from.)
