Boiling hops

I have been told that we add hops at the beginning of a 1 hour boil to extract the hoppy goodness (bitterness) .But we cant add all our malt to the boil as it interferes with extraction. So why not just boil or steep the hops in water and add to the wort?

Because hop “tea” made with water is nasty and grassy - boiling with wort extracts the hop qualities we want.
