Because it won't work. Take a look at make.conf(5) manual page - 
USE_ORDER="env:pkg:conf:defaults:pkginternal:env.d" - USE defaults in profile 
will override pkginternal (IUSE defaults in ebuild).
That being said IUSE="-foo" is no-op.

Otherwise I agree with you wrt naming inconsistencies.

I would also like to see some USE defaults from make.defaults moved to 
package.use, and some package.use defaults moved to IUSE defaults (and some 
make.defaults dropped completely, like freaking python and perl USE flags - 
bug 250179)
