There's no valid technical reason why an app *must* use hal. An app can try
and do all hardware detection by itself, but it just makes more sense to use
one common layer for that rather than every app doing essentially the same
KDE-4 itself does not directly require hal. Solid does though:
$ equery depends hal

There's nothing wrong with the *idea* of hal; it's the implementation of that
app that makes it an utter piece of shit. It's called "feature-creep".
Even it's author knows this (but apparently many distros do not) which is why
he deprecated hal and started over with devicekit.
