What is so interesting about heavily scented laundry products of today is that there is also a strong "no scent" movement in some offices, etc. I gather the no scent is more a perfume/cologne/heavily scented lotion/etc issue, due to sensitivities some people have. But it seems like laundry detergent that leaves clothes smelling like they'd been doused in a couple of gallons of cheap perfume might also be an issue in "no scent" environments.
Of course, there are unscented laundry products, and that's my personal preference during line drying season. Line dried clothes have a nice scent, better than anything any detergent company has come up with. Unless, of course, one lives next door to a pig farm or something. But I like LIGHTLY scented products--an endangered species, it seems--for winter when stuff is dried, one way or another, inside.
