As a female I don't actually find soft, female bellies unattractive at all. Especially with curvy hips and a tiny waist, it has always read as feminine softness to me, not a spare tire. I think it definitely gets more fixation than it deserves - generally only young, childless women have that flat belly, and while I understand the fixation with youth, expecting or desiring an older woman to have the same shape is unrealistic.
I think strength training and further reducing innsize will indeed minimize it, but unless your body fat wss unhealthily low, I wouldn't expect it to go away. It's part of the fat distribution on the female body!
That said, my own lower belly definitely needs to shrink in size. A little fat and sagging skin wouldn't bother me, but right now I am losing everywhere but there (partially thanks to breastfeeding, it preserves belly fat stores for hormonal reasons) and so my ribs are a size 14 and my lower belly remains a full 18. It's annoying, to say the least. My only hope is that as I am continuing down the scale, it will have no choice but to reduce a bit
