We're adding a new vector target, so have the opposite concern. We want to 
prevent sloppy code from ever appearing. Other toolchains implementing the 
ARM NEON extensions disallow these conversions, so allowing them in gcc is 
not advantageous. I've been told by contacts at ARM that they believe there 
is value in strict checking of vector types.

I've no idea if there are significant quantities of code out there that rely 
on implicit conversions.
