Lets not turn this into a discussion about religion. Some prefer
UA-detection, others feature detection. Specifications are meant to
specify how browsers behave, also in edge-cases. So developers don't
have to fight with browser differences.

I'm not saying the user should not be able to choose, but rather that
this is how browsers behave today. Developers find it useful, and I
think that makes it valuable in the specification. If I have a site
that loads scripts on demand, why should a desktop user without touch
hardware load touch-specific scripts?
