Companion moss?

I understand Sepp Holtzer recommends white clover as companion plant for the food forest, but after a little consideration, I've found that moss makes for beautiful ground cover and accommodates my sensitive feet in this extra-rocky ground in south west Missouri.

Would it be foolish to put down grundles of moss where white clover would otherwise be put? Thoughts, please?

There is a nursery here locally that uses moss as ground cover. They keep a nice path through the couple acre property clear of leaves. But it only really works year-round with a closed canopy in my area. Partly sunny areas make the moss die back for the summer. I have a pretty patch in a shady-ish area... It's gone once the annual grasses need a trim. For me, transplanting has always ended in failure. I've not tried any purchased varieties. Maybe there is something out there intended for full sun?

One of the benefits of the clover is nitrogen fixation. There are mosses that do this, but leaf litter inhibits the process. I like to leave the leaves in place to break down. Some info on nitrogen-fixing moss, found on PERMIES! Who'd of guessed?
