I think because:
1.) More precision -> more resources -> more expensive chip (you know
how competitive market is today !)
2.) More precision -> slower design -> ...
3.) Most ordinary customers need only single precision anyway (rocket
scientists are not ordinary customers IMO ;-)

But of course I might be wrong and it is not so simple to scale to
double precision just by modifying vector size. Anyone?
