Another use for minions is drawing fire or providing support.
The PCs have to waste actions shooting at them, thus giving the higher level things more room. If the PCs don't clear them out first, the minions can flank with more serious monsters, or provide Aid Another.
I ran the end battle of KotS, and placed about 10 minions in the fight. They really annoyed the players, because they weren't clumped up, and just fired their bows at PCs who hurt the real monsters last. They rolled REAL well - characters were taking at least 10 damage a turn from the minions.
But then, I don't give a lot of XP for minions period. I just toss them in to add flavor to an encounter.
