The WPKG process will definitely run in 32-bit mode.
The difference is how good the installers are developed.
Do they still install the 64-bit software, when run in 32-bit context?

In addition it depends on the software itself, if it is beneficial to 
run the 64-bit software on 64-bit systems.

High end software like video, CAD design, image processing will benefit 
from utilizing all available RAM.
Desktop publishing usually can live with the 4GiB maximum for 32-bit 
software on 64-bit systems.

Finally remember that 16-bit support vanished, so will 32-bit support 
vanish when its time comes.
