The x86 biarch tends to be an after thought.  But we
have to do the hard work for all of the architectures
where the optimal configuration is 32bit userspace with
a 64bit kernel.  So we might as well have it work on
x86 so we can test the code without need an exotic

In my case it was purely code size savings on an embedded
setup that got me using, and thus fixing it.
