This seam really can make a big difference to the fit. For those of you with a flat butt or for the larger backside in relation to relatively thin legs, this seam is a life-saver! Team that up with a horizontal fish-eye dart and you've got a winner.

Here's a close-up.
I think you can see the seam a little better in this close-up. The fabric has kind of a waffle-like texture and honestly, the seam just simply gets lost.
Once you've refined your personal pants blueprint to include this seam and the horizontal fish-eye dart, just use your pattern over and over again. Two extra seams takes no time at all to sew. Just change the style of waist edge treatment, the opening details, width of leg and finished length - they all will give you satisfaction.

It's not too long. Please take a look if you haven't watched it before.
If you so choose, when you're sewing this center leg seam, leave a 4" or 5" slit/vent open at the hem level. Yes, you are emphasizing the seam, but now the design all looks like an intended variation.
